Splice-aware RNA-seq aligner producing sorted BAM and splice junction tables. Builds genome index, runs two-pass alignment for better junctions. Outputs sorted BAM, junctions (SJ.out.tab), stats (Log.final.out), optional gene counts. Use Salmon for fast pseudoalignment; STAR when a BAM is needed for variant calling, IGV, or ENCODE pipelines.
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
# STAR — Spliced RNA-seq Aligner ## Overview STAR (Spliced Transcripts Alignment to a Reference) aligns RNA-seq reads to a genome in a splice-aware manner, identifying novel and annotated splice junctions in a single pass. It generates coordinate-sorted BAM files compatible with samtools, IGV, deeptools, and GATK. STAR's 2-pass mode re-aligns reads using junctions discovered in the first pass, improving sensitivity for novel splice sites. With `--quantMode GeneCounts`, STAR simultaneously produces gene-level read count tables without requiring a separate featureCounts or HTSeq step. ## When to Use - Aligning bulk RNA-seq reads to a reference genome when downstream tools require a BAM file (variant calling, visualization, deeptools) - Running ENCODE-compliant RNA-seq pipelines that mandate genome alignment - Discovering novel splice junctions and alternative splicing events in the dataset - Generating gene count tables alongside BAM alignment in a single step with `--quantMode GeneCounts` - Processing long reads or reads with high mismatch rates by tuning `--outFilterMismatchNmax` …

How to install
mdr add jaechang-hits/sciagent-skills/star-rna-seq-aligner@sha256:bfd5bfbcc5b31551The line at the top of this page pins the label git:20260929.7a7d60f, 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.
