End-to-end bulk RNA-seq quantification with omicverse's alignment module — SRA download, fastp QC, two interchangeable quantification paths (STAR + featureCount, OR alignment-free kb-python with technology='BULK'), and wiring into `ov.bulk.pyDEG` DESeq2. Single-cell kb-python (10XV2/10XV3) is out of scope — use the `single-cell-kb-alignment` skill instead.
