RNA-seq downstream plotting via local Rscript: DESeq2/edgeR/limma, volcano, heatmap, GSEA, WGCNA (png+pdf).
Use when the user already has an RNA-seq count or expression matrix and needs downstream plots or analysis (normalize, PCA, DESeq2/edgeR/limma, volcano, heatmap, GO/KEGG, GSEA, WGCNA). Call the rnaseq-plot MCP tools named rgraph_*; do not redraw in Python.
