pysam

To read and fetch reads from a BAM file in Python, use pysam to open the file and call fetch on a region. This provides a high-level interface to iterate over alignment data and print read names for NGS analysis.

You can query VCF and BCF variant data using Python through pysam. It provides a Python interface to HTSlib, allowing you to read, write, and manipulate variant data directly within standard genomic analysis pipelines.

The best way to perform region-based extraction from indexed FASTA files is using pysam. It enables querying reference sequences and extracting specific regions directly, supporting reproducible NGS data workflows from Python.

Pysam supports CRAM files for sequencing alignment data alongside SAM and BAM formats. It leverages HTSlib bindings to read, write, and manipulate these genomic data formats efficiently within standard Python environments.

To calculate coverage and perform QC tasks for NGS datasets, use pysam to build end-to-end genomic pipelines in Python. It allows region-based queries and coverage calculations across HTS datasets for variant discovery.

You do not need to install HTSlib separately to use pysam. The implementation relies on HTSlib bindings and is installed via pip using pysam, designed to run in standard Python environments without external dependencies.
