SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires star, samtools, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill automates the process of aligning RNA sequencing reads to a reference genome, a crucial step for analyzing gene expression and discovering novel transcripts.

Core Features & Use Cases

Splice-aware Alignment: Accurately maps RNA reads, identifying both known and novel splice junctions.
Genome Indexing: Generates necessary index files for efficient alignment.
Output Generation: Produces coordinate-sorted BAM files, splice junction tables, and alignment statistics. Optionally generates gene count tables.
Use Case: Analyze bulk RNA-seq data to identify differentially expressed genes by aligning raw reads to a reference genome and generating gene count matrices.

Quick Start

Align paired-end RNA-seq reads using the STAR aligner with a pre-generated genome index.

High-intent search queries and answers about installing and using this skill.

FAQPage Schema

How do I align RNA-seq reads to a reference genome?▼

To align RNA-seq reads, this Skill performs splice-aware alignment using the STAR aligner, accurately mapping reads and identifying both known and novel splice junctions to generate coordinate-sorted BAM files.

How do I generate a genome index for RNA-seq alignment?▼

Generating a genome index for RNA-seq alignment is handled by this Skill's genome indexing feature, which creates the necessary index files required by the STAR aligner for efficient read mapping to the reference genome.

What outputs do I get from RNA-seq alignment with STAR?▼

RNA-seq alignment with STAR produces coordinate-sorted BAM files, splice junction tables, and alignment statistics, and optionally generates gene count matrices for downstream differential gene expression analysis.

Does this RNA-seq aligner support downstream variant calling?▼

Yes, this RNA-seq aligner supports downstream variant calling by producing coordinate-sorted BAM output files that are fully compatible with downstream variant callers and visualization platforms.

Can I use STAR for bulk RNA-seq differential expression analysis?▼

Yes, you can use STAR for bulk RNA-seq differential expression analysis by aligning raw reads to a reference genome and generating gene count matrices to identify differentially expressed genes.

Do I need samtools to perform splice-aware RNA-seq alignment?▼

Yes, samtools is required alongside the STAR aligner dependency to process, coordinate-sort, and manage the BAM output files generated during splice-aware RNA-seq alignment.
