PySam provides a powerful Python interface for low-level, streaming access to HTSlib-supported genomic data formats. It enables reading, querying, filtering, and writing complex formats such as SAM/BAM/CRAM, VCF/BCF, FASTA/FASTQ, and tabix-indexed tables. It is essential for bioinformatics pipelines requiring precise control over genomic data manipulation, including pileup and coverage calculations.
