IHM Meeting Summary Oct 11, 2017

Attended by Ben Webb, Tom Goddard and Brinda Vallat

1. New depositions - Diubuquitin (ready for release) and Human Serum Albumin (HSA, in process). Both are atomic models. Chimera and other software require _atom_site.pdbx_PDB_model_num in addition to _atom_site.ihm_model_id. The dictionary will be updated to create a new parent-child relationship between _atom_site.pdbx_PDB_model_num and _ihm_model_list.ihm_model_id.

2. Issue 43: Dictionary has been updated to include ihm_model_representative category. Recommendations for grouping models will be added in the dictionary.

3. IHM_ENSEMBLE_INFO category: At present, this category assumes that an ensemble corresponds to one model group (as defined in IHM_MODEL_LIST category) and/or one external file (as defined in IHM_EXTERNAL_FILES category), if any. In order to allow for an ensemble to comprise of more than one model group and/or more than one external file, _ihm_ensemble_info.ordinal_id could be introduced in the category as the category key.

4. IHM_DATASET_LIST category: Predicted contacts is a generic data type (Issue 41). Specific information regarding contacts predicted from evolutionary coupling data and high-throughput sequencing methods needs to be captured. In addition, the enumerations in _ihm_dataset_list.data_type should be made consistent to represent experiment type and/or data type.

5. Issues 46 and 47 will be discussed next week. Issue 44 will be addressed after Tom provides his recommendations from visualizing the Fly Genome structure with ChimeraX.

6. Issue 39: The PDB-Dev accession codes will be of the form PDBDEV_XXXXXXXX.

7. Next meeting is scheduled for Thursday, October 19th at 12:00 PM Eastern time. The meeting in two weeks has been rescheduled to Wednesday, October 25th at 12:00 PM Eastern time.
