EsMeCaTa is a method to estimate metabolic capabilities from a taxonomic affiliation (for example with 16S rRNA sequencing or using a specific taxon name) by using the UniProt Proteomes database. This can be used to (1) estimate protein sequences and functions for an organism with no sequenced genomes, (2) explore the protein diveristy of a taxon.

EsMeCaTa is developed in Python, it is tested with Python 3.11. It needs the following python packages:
- biopython: To create fasta files and used by the option
--annotation-filesto index UniProt flat files. - pandas: To read the input files.
- requests: For the REST queries on Uniprot.
- ete3: To analyse the taxonomic affiliation and extract taxon_id, also used to deal with taxon associated with more than 100 proteomes.
- SPARQLwrapper: Optionally, you can use SPARQL queries instead of REST queries. This can be done either with the Uniprot SPARQL Endpoint (with the option
--sparql uniprot) or with a Uniprot SPARQL Endpoint that you created locally (it is supposed to work but not tested, only SPARQL queries on the Uniprot SPARQL endpoint have been tested). Warning: using SPARQL queries will lead to minor differences in functional annotations and metabolic reactions due to how the results are retrieved with REST query or SPARQL query.
Also esmecata requires mmseqs2 for protein clustering with esmecata workflow or esmecata clustering:
- mmseqs2: To cluster proteins. Test have been made on version MMseqs2 Release 13-45111., especially with the version of the commit f349118312919c4fcc448f4595ca3b3a387018e2. But EsMeCaTa should be compatible with more recent version.
And eggnog-mapper for the annotation of the protein with esmecata workflow or esmecata annotation:
- eggnog-mapper: to annotate protein clusters. It needs a path to the eggnog database. Also according to the option used, it needs around 60 Gb of RAM. So it is recommended to use it in a cluster.
If you use the option --bioservices, EsMeCaTa will also require this package:
- bioservices: To query Uniprot instead of using the query functions of EsMeCaTa (potentially more robust overtime).
To query the precomputed database, it is only required to install EsMeCaTa with pip:
pip install esmecata
All the required dependencies for the estimation from the precomputed database are performed with python packages.
For the whole workflow, the easiest way to install the dependencies of EsMeCaTa is by using conda (or mamba):
conda install mmseqs2 pandas sparqlwrapper requests biopython ete3 eggnog-mapper -c conda-forge -c bioconda
EsMeCaTa is available on PyPI and can be installed with pip:
pip install esmecata
It can also be installed using esmecata github directory:
git clone https://github.com/ArnaudBelcour/esmecata.git
cd esmecata
pip install -e .
To use eggnog-mapper, you have to setup it and install its database, refer to the setup part of the doc.
esmecata_report requires:
Warning: due to the fact that datapane is no longer maintained, it requires a version of pandas lower than 2.0.0. esmecata_report has been used with pandas 1.5.3.
The replacement of datapane by panel is under development to solve this issue.
esmecata_gseapy requires:
- pronto: to get Gene Ontology names.
- gseapy: to perform enrichment analysis.
- orsum: to visualize the results of enrichment analysis.
All dependencies can be installed with following command:
conda install mmseqs2 pandas=1.5.3 sparqlwrapper requests biopython ete3 eggnog-mapper orsum gseapy plotly datapane python-kaleido -c conda-forge -c bioconda
EsMeCaTa takes as input a tabulated or an excel file with two columns one with the ID corresponding to the taxonomic affiliation (for example the OTU ID from 16S rRNA sequencing) and a second column with the taxonomic classification separated by ';'. In the following documentation, the first column (named observation_name) will be used to identify the label associated with each taxonomic affiliation. An example is located in the test folder (Example.tsv).
For example:
| observation_name | taxonomic_affiliation |
|---|---|
| Cluster_1 | Bacteria;Spirochaetes;Spirochaetia;Spirochaetales;Spirochaetaceae;Sphaerochaeta;unknown species |
| Cluster_2 | Bacteria;Chloroflexi;Anaerolineae;Anaerolineales;Anaerolineaceae;ADurb.Bin120;unknown species |
| Cluster_3 | Bacteria;Cloacimonetes;Cloacimonadia;Cloacimonadales;Cloacimonadaceae;Candidatus Cloacimonas;unknown species |
| Cluster_4 | Bacteria;Bacteroidetes;Bacteroidia;Bacteroidales;Rikenellaceae;Rikenellaceae RC9 gut group;unknown species |
| Cluster_5 | Bacteria;Cloacimonetes;Cloacimonadia;Cloacimonadales;Cloacimonadaceae;W5;unknown species |
| Cluster_6 | Bacteria;Bacteroidetes;Bacteroidia;Bacteroidales;Dysgonomonadaceae;unknown genus;unknown species |
| Cluster_7 | Bacteria;Firmicutes;Clostridia;Clostridiales;Clostridiaceae;Clostridium;unknown species |
It is possible to use EsMeCaTa with a taxonomic affiliation containing only one taxon:
| observation_name | taxonomic_affiliation |
|---|---|
| Cluster_1 | Sphaerochaeta |
| Cluster_2 | Yersinia |
But this can cause issue. For example, "Cluster_2" is associated with Yersinia but two genus are associated with this name (one mantid (taxId: 444888) and one bacteria (taxId: 629)). EsMeCaTa will not able to differentiate them. But if you give more informations by adding more taxons (for example: 'Bacteria;Gammaproteobacteria;Yersinia'), EsMeCaTa will compare all the taxons of the taxonomic affiliation (here: 2 (Bacteria) and 1236 (Gammaproteobacteria)) to the lineage associated with the two taxIDs (for bacteria Yersinia: [1, 131567, 2, 1224, 1236, 91347, 1903411, 629] and for the mantid one: [1, 131567, 2759, 33154, 33208, 6072, 33213, 33317, 1206794, 88770, 6656, 197563, 197562, 6960, 50557, 85512, 7496, 33340, 33341, 6970, 7504, 7505, 267071, 444888]). In this example, there is 2 matches for the bacterial one (2 and 1236) and 0 for the mantid one. So EsMeCaTa will select the taxId associated with the bacteria (629).
A jupyter notebook explains how EsMeCata works.
Several command line are created after the isntallation:
esmecata: the main command to perform esmecata workflow from input file or with a precomputed database.esmecata_report: another command to create HTML report showing different statistics on the predictions.esmecata_gseapy: to perform enrichment analysis using gseapy and orsum to identify functions specific to some taxa compare to the all community.esmecata_create_db: to create precomputed databases from an esmecata run or merge different precomputed databases.
Here is the help for the main esmecata command:
usage: esmecata [-h] [--version] {check,proteomes,clustering,annotation_uniprot,annotation,workflow_uniprot,workflow,precomputed} ...
From taxonomic affiliation to metabolism using Uniprot. For specific help on each subcommand use: esmecata {cmd} --help
options:
-h, --help show this help message and exit
--version show program's version number and exit
subcommands:
valid subcommands:
{check,proteomes,clustering,annotation_uniprot,annotation,workflow_uniprot,workflow,precomputed}
check Check proteomes associated with taxon in Uniprot Proteomes database.
proteomes Download proteomes associated with taxon from Uniprot Proteomes.
clustering Cluster the proteins of the different proteomes of a taxon into a single set of representative shared proteins.
annotation_uniprot Retrieve protein annotations from Uniprot.
annotation Annotate protein clusters using eggnog-mapper.
workflow_uniprot Run all esmecata steps (proteomes, clustering and annotation).
workflow Run all esmecata steps (proteomes, clustering and annotation with eggnog-mapper).
precomputed Use precomputed database to create estimated data for the run.
Steps proteomes and annotation by UniProt requires an internet connection (for REST and SPARQL queries, except if you have a local Uniprot SPARQL endpoint). Step clustering requires mmseqs2. Annotation can be performed with UniProt or eggnog-mapper (which is then a requirement if the option is selected). Precomputed requires the esmecata_database.zip file.
WARNING: Database is in development, it is not available yet. But there are several precomputed databases associated with the article datasets available in the Zenodo archive of EsMeCaTa.
Using the precomputed database, esmecata searches for input taxon inside the precomputed database to make prediction. It requires an input file containing the taxonomic affiliations and a precomputed esmecata database. For each observation name in the input file, it will returned the associated annotations. It will also output the protein sequences for each taxa associated with the observation name.
usage: esmecata precomputed [-h] -i INPUT_FILE -d INPUT_FILE -o OUPUT_DIR [-r RANK_LIMIT] [--update-affiliations]
options:
-h, --help show this help message and exit
-i INPUT_FILE, --input INPUT_FILE
Input taxon file (excel, tsv or csv) containing a column associating ID to a taxonomic affiliation (separated by ;).
-d INPUT_FILE, --database INPUT_FILE
EsMeCaTa precomputed database file path.
-o OUPUT_DIR, --output OUPUT_DIR
Output directory path.
-r RANK_LIMIT, --rank-limit RANK_LIMIT
This option limits the rank used when searching for proteomes. All the ranks superior to the given rank will be ignored. For example, if 'family' is given, only taxon ranks inferior or equal to family will be kept. Look at the readme for more
information (and a list of rank names).
--update-affiliations
If the taxonomic affiliations were assigned from an outdated taxonomic database, this can lead to taxon not be found in ete3 database. This option tries to udpate the taxonomic affiliations using the lowest taxon name.
Two options can be used to limit the rank used when searching for proteomes and to update the taxonomic affiliations from the input file.
Example of use:
esmecata precomputed -i input_taxonomic_affiliations.tsv -d esmecata_database.zip -o output_folder
Otherwise, it is possible to run the whole workflow of EsMeCaTa but it will take times as it will search and download proteomes from UniProt, clsuter protein sequences with mmseqs2 and then annotate them with eggnog-mapper.
These different steps are presented in the following section.
EsMeCaTa is in three steps:
proteomes: search for proteomes associated with the taxonomic affiliations on UniProt (also done withchecksubcommand) and download them.clustering: clusters the protein of the proteomes and filter them according to a threshold -option (-t).annotation: annotate the protein cluster.
The annotation step can be performed with two methods, either by retrieving annotation from UniProt or by using eggnog-mapper.
The eggnog-mapper approach has been found to be the more accurate in association with a clustering threshold of 0.5 (-t 0.5).
These options are the default options of EsMeCaTa.
As these steps can required time, a precomputed database has been created containing taxa of species, genus, family, order, class and phylum having at least 5 proteomes in UniProt.
This precomputed database can be used with the command esmecata precomputed to search the taxonomic affiliations from the input file into the database.
usage: esmecata check [-h] -i INPUT_FILE -o OUPUT_DIR [-b BUSCO] [--ignore-taxadb-update] [--all-proteomes] [-s SPARQL] [-l LIMIT_MAXIMAL_NUMBER_PROTEOMES] [-r RANK_LIMIT] [--minimal-nb-proteomes MINIMAL_NUMBER_PROTEOMES] [--update-affiliations] [--bioservices]
options:
-h, --help show this help message and exit
-i INPUT_FILE, --input INPUT_FILE
Input taxon file (excel, tsv or csv) containing a column associating ID to a taxonomic affiliation (separated by ;).
-o OUPUT_DIR, --output OUPUT_DIR
Output directory path.
-b BUSCO, --busco BUSCO
BUSCO percentage between 0 and 1. This will remove all the proteomes without BUSCO score and the score before the selected ratio of completion.
--ignore-taxadb-update
If you have a not up-to-date version of the NCBI taxonomy database with ete3, use this option to bypass the warning message and use the old version.
--all-proteomes Download all proteomes associated with a taxon even if they are no reference proteomes.
-s SPARQL, --sparql SPARQL
Use sparql endpoint instead of REST queries on Uniprot.
-l LIMIT_MAXIMAL_NUMBER_PROTEOMES, --limit-proteomes LIMIT_MAXIMAL_NUMBER_PROTEOMES
Choose the maximal number of proteomes after which the tool will select a subset of proteomes instead of using all the available proteomes (default is 99).
-r RANK_LIMIT, --rank-limit RANK_LIMIT
This option limits the rank used when searching for proteomes. All the ranks superior to the given rank will be ignored. For example, if 'family' is given, only taxon ranks inferior or equal to family will be kept. Look at the readme for more
information (and a list of rank names).
--minimal-nb-proteomes MINIMAL_NUMBER_PROTEOMES
Choose the minimal number of proteomes to be selected by EsMeCaTa. If a taxon has less proteomes, it will be ignored and a higher taxonomic rank will be used. Default is 5.
--update-affiliations
If the taxonomic affiliations were assigned from an outdated taxonomic database, this can lead to taxon not be found in ete3 database. This option tries to udpate the taxonomic affiliations using the lowest taxon name.
--bioservices Use bioservices instead of esmecata functions for protein annotation.
For each taxon in each taxonomic affiliations EsMeCaTa will use ete3 to find the corresponding taxon ID. Then it will search for proteomes associated with these taxon ID in the Uniprot Proteomes database.
If there is more than 100 proteomes, esmecata will apply a specific method:
-
(1) use the taxon ID associated with each proteomes to create a taxonomic tree with ete3.
-
(2) from the root of the tree (the input taxon), esmecata will find the direct deescendant (sub-taxons).
-
(3) then esmecata will compute the number of proteomes associated with each sub-taxon.
-
(4) the corresponding proportions will be used to select randomly a number of proteomes corresponding to the proportion.
For example: for the taxon Clostridiales, 645 proteomes are found. Using the organism taxon ID associated with the 645 proteomes we found that there is 17 direct sub-taxons. Then for each sub-taxon we compute the percentage of proportion of proteomes given by the sub-taxon to the taxon Clostridiales.
There is 198 proteomes associated with the sub-taxon Clostridiaceae, the percentage will be computed as follow: 198 / 645 = 30% (if a percentage is superior to 1 it will be round down and if the percentage is lower than 1 it will be round up to keep all the low proportion sub-taxons). We will use this 30% to select randomly 30 proteomes amongst the 198 proteomes of Clostridiaceae. This is done for all the other sub-taxons, so we get a number of proteomes around 100 (here it will be 102). Due to the different rounds (up or down) the total number of proteomes will not be equal to exactly 100 but it will be around it. The number of proteomes leading to this behavior is set to 99 by default but the user can modify it with the -l/--limit-proteomes option.
esmecata check options:
-s/--sparql: use SPARQL instead of REST requests
It is possible to avoid using REST queries for esmecata and instead use SPARQL queries. This option need a link to a sparql endpoint containing UniProt. If you want to use the SPARQL endpoint of UniProt, you can use the argument: -s uniprot.
-b/--busco: filter proteomes using BUSCO score (default is 0.8)
It is possible to filter proteomes according to to their BUSCO score (from Uniprot documentation: The Benchmarking Universal Single-Copy Ortholog (BUSCO) assessment tool is used, for eukaryotic and bacterial proteomes, to provide quantitative measures of UniProt proteome data completeness in terms of expected gene content.). It is a percentage between 0 and 1 showing the quality of the proteomes that esmecata will download. By default esmecata uses a BUSCO score of 0.80, it will only download proteomes with a BUSCO score of at least 80%.
--ignore-taxadb-update: ignore need to udpate ete3 taxaDB
If you have an old version of the ete3 NCBI taxonomy database, you can use this option to use esmecata with it.
--all-proteomes: download all proteomes (reference and non-reference)
By default, esmecata will try to downlaod the reference proteomes associated with a taxon. But if you want to download all the proteomes associated with a taxon (either if they are non reference proteome) you can use this option. Without this option non-reference proteoems can also be used if no reference proteomes are found.
-l/--limit-proteomes: choose the number of proteomes that will lead to the used of the selection of a subset of proteomes
To avoid working on too many proteomes, esmecata works on subset of proteomes when there is too many proteomes (by default this limit is set on 99 proteomes). Using this option the user can modify the limit.
--minimal-nb-proteomes: choose the minimal number of proteomes that taxon must have to be selected by esmecata (default 1).
To avoid working on too little proteomes, it is possible to give an int to this option.
With this int, esmecata will select only taxon associated to at least this number of proteomes.
For example if you use --minimal-nb-proteomes 10, and the lowest taxon in the taxonomic affiliation is associated with 3 proteomes, it will be ignored and a taxon with a higer taxonomic rank will be used.
-r/--rank-limit: This option limits the rank used when searching for proteomes. All the ranks superior to the given rank will be ignored. For example, if 'family' is given, only taxon ranks inferior or equal to family will be kept.
To avoid working on rank with too much proteomes (which can have an heavy impact on the number of proteomes downloaded and then on the clustering) it is possible to select a limit on the taxonomic rank used by the tool.
The selected rank will be used to find the ranks to keep. For example, if the rank 'phylum' is given, this rank and all the rank below (from phylum to isolate) will be kept. And the ranks from superphylum to superkingdom will be ignored when searching for proteomes. The following ranks can be given to this option (from Supplementary Table S3 of PMC7408187):
| Level | Rank |
|---|---|
| 1 | superkingdom |
| 2 | kingdom |
| 3 | subkingdom |
| 4 | superphylum |
| 5 | phylum |
| 6 | subphylum |
| 7 | infraphylum |
| 8 | superclass |

| 17 | infraorder |
| 18 | parvorder |
| 19 | superfamily |
| 20 | family |
| 21 | subfamily |
| 22 | tribe |

| 36 | subvariety |
| 37 | forma |
| 38 | serogroup |
| 39 | serotype |
| 40 | strain |
| 41 | isolate |
Some ranks (which are not non-hierarchical) are not used for the moment when using this method (so some taxa can be removed whereas they are below a kept rank):
| Level | Rank | Note |
|---|---|---|
| clade | newly introduced, can appear anywhere in the lineage w/o breaking the order | |
| environmental samples | no order below this rank is required | |
| incertae sedis | can appear anywhere in the lineage w/o breaking the order, implies taxa with uncertain placements | |
| unclassified | no order below this rank is required, includes undefined or unspecified names | |
| no rank | applied to nodes not categorized here yet, additional rank and groups names will be released |
--bioservices: instead of using REST queries implemented in EsMeCaTa, relies on bioservices API to query UniProt. This requires the bioservices package.
usage: esmecata proteomes [-h] -i INPUT_FILE -o OUPUT_DIR [-b BUSCO] [--ignore-taxadb-update] [--all-proteomes] [-s SPARQL] [-l LIMIT_MAXIMAL_NUMBER_PROTEOMES] [-r RANK_LIMIT] [--minimal-nb-proteomes MINIMAL_NUMBER_PROTEOMES] [--update-affiliations] [--bioservices]
optional arguments:
-h, --help show this help message and exit
-i INPUT_FILE, --input INPUT_FILE
Input taxon file (excel, tsv or csv) containing a column associating ID to a taxonomic affiliation (separated by ;).
-o OUPUT_DIR, --output OUPUT_DIR
Output directory path.
-b BUSCO, --busco BUSCO
BUSCO percentage between 0 and 1. This will remove all the proteomes without BUSCO score and the score before the selected ratio of completion.
--ignore-taxadb-update
If you have a not up-to-date version of the NCBI taxonomy database with ete3, use this option to bypass the warning message and use the old version.
--all-proteomes Download all proteomes associated with a taxon even if they are no reference proteomes.
-s SPARQL, --sparql SPARQL
Use sparql endpoint instead of REST queries on Uniprot.
-l LIMIT_MAXIMAL_NUMBER_PROTEOMES, --limit-proteomes LIMIT_MAXIMAL_NUMBER_PROTEOMES
Choose the maximal number of proteomes after which the tool will select a subset of proteomes instead of using all the available proteomes (default is 99).
-r RANK_LIMIT, --rank-limit RANK_LIMIT
This option limits the rank used when searching for proteomes. All the ranks superior to the given rank will be ignored. For example, if 'family' is given, only taxon ranks inferior or equal to family will be
kept. Look at the readme for more information (and a list of rank names).
--minimal-nb-proteomes MINIMAL_NUMBER_PROTEOMES
Choose the minimal number of proteomes to be selected by EsMeCaTa. If a taxon has less proteomes, it will be ignored and a higher taxonomic rank will be used. Default is 1.
--update-affiliations
If the taxonomic affiliations were assigned from an outdated taxonomic database, this can lead to taxon not be found in ete3 database. This option tries to udpate the taxonomic affiliations using the lowest taxon
name.
--bioservices Use bioservices instead of esmecata functions for protein annotation.
EsMeCaTa proteomes performs the same action than esmecata check and after this step, it downloads the proteomes. For protein with isoforms, the canonical sequence is retrieved except when the isoforms are separated in different Uniprot entries.
usage: esmecata clustering [-h] -i INPUT_DIR -o OUPUT_DIR [-c CPU] [-t THRESHOLD_CLUSTERING] [-m MMSEQS_OPTIONS] [--linclust] [--remove-tmp]
optional arguments:
-h, --help show this help message and exit
-i INPUT_DIR, --input INPUT_DIR
This input folder of clustering is the output folder of proteomes command.
-o OUPUT_DIR, --output OUPUT_DIR
Output directory path.
-c CPU, --cpu CPU CPU number for multiprocessing.
-t THRESHOLD_CLUSTERING, --threshold THRESHOLD_CLUSTERING
Proportion [0 to 1] of proteomes required to occur in a proteins cluster for that cluster to be kept in core proteome assembly.
-m MMSEQS_OPTIONS, --mmseqs MMSEQS_OPTIONS
String containing mmseqs options for cluster command (except --threads which is already set by --cpu command and -v). If nothing is given, esmecata will used the option "--min-seq-id 0.3 -c 0.8"
--linclust Use mmseqs linclust (clustering in lienar time) to cluster proteins sequences. It is faster than mmseqs cluster (default behaviour) but less sensitive.
--remove-tmp Delete tmp files to limit the disk space used: files created by mmseqs (in mmseqs_tmp).
For each taxon (a row in the table) EsMeCaTa will use mmseqs2 to cluster the proteins (using an identity of 30% and a coverage of 80%, these values can be changed with the --mmseqsoption). Then if a cluster contains at least one protein from each proteomes, it will be kept (this threshold can be changed using the --threshold option). The representative proteins from the cluster will be used. A fasta file of all the representative proteins will be created for each taxon.
esmecata clustering options:
-t/--threshold: clustering threshold
It is possible to modify the requirements of the presence of at least one protein from each proteomes in a cluster to keep it. Using the threshold option one can give a float between 0 and 1 to select the ratio of representation of proteomes in a cluster to keep.
For example a threshold of 0.8 means that all the cluster with at least 80% representations of proteomes will be kept (with a taxon, associated with 10 proteomes, it means that at least 8 proteomes must have a protein in the cluster so the cluster must be kept).
-c/--cpu: number of CPU for mmseqs2
You can give a numbe of CPUs to parallelise mmseqs2.
-m/--mmseqs: mmseqs option to be used for the clustering.
String containing mmseqs options for cluster command (except --threads which is already set by --cpu command and -v). If nothing is given, esmecata will used the option "--min-seq-id 0.3 -c 0.8". For example you can give --mmseqs "--min-seq-id 0.8 --kmer-per-seq 80" to ask for a minimal identity between sequence of 80% and having 80 kmers per sequence.
--linclust: replacemmseqs clusterbymmseqs linclust(faster but less sensitive)
Use mmseqs linclust (clustering in linear time) to cluster proteins sequences. It is faster than mmseqs cluster (default behaviour) but less sensitive.
--remove-tmp: remove mmseqs files stored inmmseqs_tmpfolder
usage: esmecata annotation [-h] -i INPUT_DIR -o OUPUT_DIR -e EGGNOG_DATABASE [-c CPU] [--eggnog-tmp EGGNOG_TMP_DIR]
options:
-h, --help show this help message and exit
-i INPUT_DIR, --input INPUT_DIR
This input folder of annotation is the output folder of clustering command.
-o OUPUT_DIR, --output OUPUT_DIR
Output directory path.
-e EGGNOG_DATABASE, --eggnog EGGNOG_DATABASE
Path to eggnog database.
-c CPU, --cpu CPU CPU number for multiprocessing.
--eggnog-tmp EGGNOG_TMP_DIR
Path to eggnog tmp dir.
Requires eggnog-mapper in the path and the path to the eggnog database.
This command takes as input the folder created by esmecata clustering and uses especially the reference_proteins_consensus_fasta folder.
This folder contains the consensus protein sequences associated with each protein clusters kept according to the clustering threshold.
These sequences are given as input to eggnog-mapper.
The number of CPU used by eggnog-mapper can be modified with -c.
By default, EsMeCaTa uses the option --dbmem of eggnog-mapper to store the database in memory, this requires around 50G of RAM.
esmecata annotation_eggnog options:
-
-e: path to the eggnog database (required). -
-c: number of CPUs to be used by eggnog-mapper. -
--eggnog-tmp: path to the folder to store eggnog temporary files (by default it is inside esmecata output folder).
usage: esmecata annotation_uniprot [-h] -i INPUT_DIR -o OUPUT_DIR [-s SPARQL] [-p PROPAGATE_ANNOTATION] [--uniref] [--expression] [--annotation-files ANNOTATION_FILES] [--bioservices]
options:
-h, --help show this help message and exit
-i INPUT_DIR, --input INPUT_DIR
This input folder of annotation is the output folder of clustering command.
-o OUPUT_DIR, --output OUPUT_DIR
Output directory path.
-s SPARQL, --sparql SPARQL
Use sparql endpoint instead of REST queries on Uniprot.
-p PROPAGATE_ANNOTATION, --propagate PROPAGATE_ANNOTATION
Proportion [0 to 1] of the occurrence of an annotation to be propagated from the protein of a cluster to the reference protein of the cluster. 0 mean the annotations from all proteins are propagated to the reference and 1 only the annotation
occurring in all the proteins of the cluster (default).
--uniref Use uniref cluster to extract more annotations from the representative member of the cluster associated with the proteins. Needs the --sparql option.
--expression Extract expression information associated with the proteins. Needs the --sparql option.
--annotation-files ANNOTATION_FILES
Use UniProt annotation files (uniprot_trembl.txt and uniprot_sprot.txt) to avoid querying UniProt REST API. Need both paths to these files separated by a ",".
--bioservices Use bioservices instead of esmecata functions for protein annotation.
For each of the protein clusters kept after the clustering, esmecata will look for the annotation (GO terms, EC number, function, gene name, Interpro) in Uniprot.
By default, esmecata will look at the annotations of each proteins from a cluster and keeps only annotation occurring in all the protein of a cluster (threshold 1 of option -p).
It is like selecting the intersection of the annotation of the cluster. This can be changed with the option -p and giving a float between 0 and 1.
Then esmecata will create a tabulated file for each row of the input file and also a folder containing PathoLogic file that can be used as input for Pathway Tools.
esmecata annotation options:
-s/--sparql: use SPARQL instead of REST requests
It is possible to avoid using REST queries for esmecata and instead use SPARQL queries. This option need a link to a sparql endpoint containing UniProt. If you want to use the SPARQL endpoint, you can just use: -s uniprot.
-p/--propagate: propagation of annotation
It is possible to modify how the annotations are retrieved. By default, esmecata will take the annotations occurring in at least all the proteins of the cluster (-p 1). But with the -p option it is possible to propagate annotation form the proteins of the cluster to the reference proteins.
This option takes a float as input between 0 and 1, that will be used to filter the annotations retrieved. This number is multiplied by the number of protein in the cluster to estimate a threshold. To keep an annotation the number of the protein having this annotation in the cluster must be higher than the threshold. For example with a threshold of 0.5, for a cluster of 10 proteins an annotation will be kept if 5 or more proteins of the cluster have this annotation.
If the option is set to 0, there will be no filter all the annotation of the proteins of the cluster will be propagated to the reference protein (it corresponds to the union of the cluster annotations). This parameter gives the higher number of annotation for proteins. If the option is set to 1, only annotations that are present in all the proteins of a cluster will be kept (it corresponds to the intersection of the cluster annotations). This parameter is the most stringent and will limit the number of annotations associated with a protein.
For example, for the same taxon the annotation with the parameter -p 0 leads to the reconstruction of a metabolic networks of 1006 reactions whereas the parameter -p 1 creates a metabolic network with 940 reactions (in this example with no use of the -p option, so without annotation propagation, there was also 940 reactions inferred).
--uniref: use annotation from uniref
To add more annotations, esmecata can search the UniRef cluster associated with the protein associated with a taxon. Then the representative protein of the cluster will be extracted and if its identity with the protein of interest is superior to 90% esmecata will find its annotation (GO Terms and EC numbers) and will propagate these annotations to the protein. At this moment, this option is only usable when using the --sparql option.
--expression: extract expression information
With this option, esmecata will extract the expression information associated with a protein. This contains 3 elements: Induction, Tissue specificity and Disruption Phenotype. At this moment, this option is only usable when using the --sparql option.
--annotation-files: use UniProt txt files instead of queyring Uniprot servers.
As the annotation step needs a high numbers of queries to UniProt servers when working with hundreds or thousands of taxonomic affliations, it can failed due to issues with the query.
A workaround (for example on a cluster), is to use the UniProt flat files containing the protein annotations.
Warning, the TrEMBL file takes a lot of space (around 150G compressed for the version 2022_05 andd 700G uncompressed).
One of the downside of this option is that it needs lof of memory to handle indexing the TrEMBL file (around 32G using Biopython indexing) and it takes several hours to parse it.
But for dataset with thousands of taxonomic affiliations, this can be compensated by the fact that queyring the indexed files is more stable than querying a server.
For this option, you should give the path to the two annotation files (both the Swiss-Prot and the TrEMBL files) separated by ,such as: --annotation-files /db/uniprot/UniProt_2022_05/flat/uniprot_sprot.dat,/db/uniprot/UniProt_2022_05/flat/uniprot_trembl.dat.
The names of the files must contained: uniprot_sprot and uniprot_trembl to be able to differentiate them.
--bioservices: instead of using REST queries implemented in EsMeCaTa, relies on bioservices API to query UniProt. This requires the bioservices package.

The cluster_founds contains one tsv file per taxon name used by EsMeCaTa. So multiple observation_name can be represented by a similar taxon name to avoid redundancy and limit the disk space used. These files contain the clustered proteins The first column contains the representative proteins of a cluster and the following columns correspond to the other proteins of the same cluster. The first protein occurs two time: one as the representative member o.f the cluster and a second time as a member of the cluster.
The computed_threshold folder contains the ratio of proteomes represented in a cluster compared to the total number of proteomes associated with a taxon. If the ratio is equal to 1, it means that all the proteomes are represented by a protein in the cluster, 0.5 means that half of the proteoems are represented in the cluster. This score is used when giving the -t argument.
The mmseqs_tmp folder contains the intermediary files of mmseqs2 for each taxon name. To save disk space, it is recommended to delete it with the option --remove-tmp.
The reference_proteins contains one tsv file per taxon name and these files contain the clustered proteins kept after clustering process. it is similar to cluster_founds but it contains only protein kept after clustering and threshold.
The reference_proteins_consensus_fasta contains the consensus proteins associated with a taxon name for the cluster kept after clustering process.
The reference_proteins_representative_fasta contains the consensus proteins associated with a taxon name for the cluster kept after clustering process.

The eggnog_output contains the resulting files of the eggnog-mapper run, three files for each taxon name. In this way, eggnog-mapper is run only one time by taxon name which reduces the redundancy if it had to be run on all the different observation_name.
The annotation_reference contains the prediction of eggnog-mapper for the consensus protein of each observation_name. To create this file, EsMeCaTa finds the taxon name associated with the observation_name and extracts the annotation (EC numbers, GO termes, KEGG reaction).
The merge_fasta folder contains merged protein sequences of the clustering step to speed up the run of eggnog-mapper.
The pathologic folder contains one sub-folder for each observation_name in which there is one PathoLogic file. There is also a taxon_id.tsv file which corresponds to a modified version of proteome_tax_id.tsv with only the observation_name and the taxon_id. This folder can be used as input to mpwt to reconstruct draft metabolic networks using Pathway Tools PathoLogic.
The file dataset_annotation_observation_name.tsv contains the EC numbers and GO Terms present in each observation name.
The file esmecata_annotation.log contains the log associated with the command.
The esmecata_metadata_annotation.json serves the same purpose as the one used in esmecata proteomes to retrieve metadata about Uniprot release at the time of the query. It also gets the metadata associated with the command used with esmecata and the dependencies.

Using the command esmecata_report, it is possible to create an html report summarising the results from an esmecata run (either from workflow or precomputed).
usage: esmecata_report [-h] [--version] {create_report,create_report_proteomes,create_report_clustering,create_report_annotation} ...
Create report files from esmecata output folder. For specific help on each subcommand use: esmecata {cmd} --help
options:
-h, --help show this help message and exit
--version show program's version number and exit
subcommands:
valid subcommands:
{create_report,create_report_proteomes,create_report_clustering,create_report_annotation}
create_report Create report from esmecata output folder of workflow or precomputed subcommands.
create_report_proteomes
Create report from esmecata output folder of proteomes subcommand.
create_report_clustering
Create report from esmecata output folder of clustering subcommand.
create_report_annotation
Create report from esmecata output folder of annotation subcommand.
Requires: datapane, plotly, kaleido, ontosunburst.
It can be used with this command:
esmecata_report create_report -i input_taxonomic_affiliations.tsv -f esmecata_precomputed_output_folder -o output_folder
It will create several files, especially a esmecata_summary.html showing several figures summarising the results of the EsMeCaTa run.
For example:
An enrichment analysis can be performed to identify functions specific to a phylum compared to the whole community of the input files by using gseapy and orsum.
usage: esmecata_gseapy [-h] [--version] {gseapy_taxon} ...
Create enrichment analysis files from esmecata results. For specific help on each subcommand use: esmecata {cmd} --help
options:
-h, --help show this help message and exit
--version show program's version number and exit
subcommands:
valid subcommands:
{gseapy_enrichr}
gseapy_enrichr Extract enriched functions from taxon using gseapy and orsum.
Requires: gseapy and orsum
gseapy_enrichr has currently two ways of use:
- by grouping observation names according to their taxonomic ranks (by default
phylum) with the parameter--grouping tax_rank. - by grouping observation names into groups defined by the user with a tsv file with the parameter
--grouping selected. The input file is given by the suer with the parameter--taxa-listand should look like this:
| Group 1 | Group 2 | Group 3 |
|---|---|---|
| Cluster_1 | Cluster_2 | Cluster_6 |
| Cluster_5 | Cluster_3 | Cluster_7 |
| Cluster_10 | Cluster_4 | Cluster_8 |
There are two parameters mandatory for both modes:
- the
-fparameter takes as input the annotation folder of esmecata (either the output folder ofesmecata annotationor the2_annotationofesmecata workflow). - the
-oparameter corresponds to the path to the output folder.
So you can either call esmecata_gseapy gseapy_enrichr with:
esmecata_gseapy gseapy_enrichr -f esmecata_annotation_output_folder -o output_folder --grouping tax_rank --taxon-rank phylum
Or by using one input file with:
esmecata_gseapy gseapy_enrichr -f esmecata_annotation_output_folder -o output_folder --grouping selected --taxa-list manually_selected_groups.tsv
Create precomputed database from esmecata output folders or merge already present precomputed databases. This command is mainly for the developers of esmecata to automatise the creation of the precomputed database. But if you want to create a precomputed database of your esmecata run for reproducibility it is also possible. For exmaple, it was used to create the precomputed databases for the dataset of the article of EsMeCaTa.
usage: esmecata_create_db [-h] [--version] {from_workflow,merge_db} ...
Create database file from esmecata run. For specific help on each subcommand use: esmecata {cmd} --help
options:
-h, --help show this help message and exit
--version show program's version number and exit
subcommands:
valid subcommands:
{from_workflow,merge_db}
from_workflow Create database from esmecata workflow output.
merge_db Merge multiple zip files corresponding to EsMeCaTa databases.
Requires: esmecata, pandas.
It can be used with this command:
esmecata_create_db from_workflow -i esmecata_workflow_output_folder -o output_folder -c 5
The precomputed database (in zip format) will be in the output_folder and named esmecata_database.zip.
To merge several precomputed databases, you can use the following command:
esmecata_create_db from_workflow -i esmecata_database_1.zip,esmecata_database_2.zip,esmecata_database_3.zip -o output_folder
