A Python3.8+ package to trim and extract flags from FASTA and FASTQ files.
- Works on both FASTA and FASTQ files.
- Selects reads based on a pattern (regex).
- Trims reads by pattern (regex), length, or single-base quality.
- Extracts parts (flags) of reads based on a pattern and stores them in the read headers.
- Generates BED file with the locations of a substring in FASTX records.
- Regular expression support fuzzy matching (fuzzy matching might affect the barber's speed).
- Parallelizes processing by splitting the fastx file in chunks.
