Generate alignment statistics using samtools flagstat, stats, depth, coverage, and mosdepth. Use when assessing alignment quality, calculating coverage, or generating QC reports.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## Version Compatibility Reference examples tested with: pysam 0.22+, samtools 1.19+ Before using code patterns, verify installed versions match. If versions differ: - Python: `pip show <package>` then `help(module.function)` to check signatures - CLI: `<tool> --version` then `<tool> --help` to confirm flags If code throws ImportError, AttributeError, or TypeError, introspect the installed package and adapt the example to match the actual API rather than retrying. # BAM Statistics **"Get alignment statistics and coverage from my BAM file"** -> Generate read counts, mapping rates, per-chromosome statistics, depth profiles, and coverage summaries. - CLI: `samtools flagstat`, `samtools stats`, `samtools depth`, `samtools coverage` (samtools) - Python: `pysam.AlignmentFile` with `pileup()` and `get_index_statistics()` (pysam) Generate alignment statistics using samtools and pysam. ## Quick Summary Commands | Question | Best tool | Why | |----------|-----------|-----| | Quick read counts by FLAG category | `samtools flagstat` | Fast; counts secondary+supp in totals | | Per-chromosome counts | `samtools idxstats` | Fast (needs index); **counts secondary+supp** | …

How to install
mdr add fridrichmethod/awesome-skills/bio-bam-statistics@sha256:fb86e671b6386f84The line at the top of this page pins the label git:20260712.2ff971b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
