Real runs

Open a real biology run.

Each one is a complete run in production: the question as it was asked, every step Propab took, and everything it made.

Take a public bulk RNA-seq study from GEO comparing treated and control samples in a human cell line (pick one with raw counts available), run a proper differential expression analysis with DESeq2 or an equivalent, and follow it with pathway enrichment. Deliver a volcano plot, a heatmap of the top genes, the ranked gene table and a short report that says which pathways move and how confident we should be.

Volcano plotHeatmapReport

End-to-end computational study of KRAS G12C. Do real computation, not mock data. Every number you report must come from code you ran. If a step fails or a tool can’t be installed, say so and use the closest working alternative. Fetch human KRAS, HRAS, NRAS and 10–15 RAS orthologs across species, align them, score per-residue conservation and build the phylogenetic tree…
