Alternative splicing affects over 95% of multi-exon human genes and is dysregulated in cancer and neurodegeneration. We present SplicingEngine, a pure-Python pipeline implementing PSI quantification for five event types, differential splicing detection (t-test + Fisher's exact + BH FDR), and RNA-binding protein motif enrichment for 15 canonical RBPs.
We present ProteomicsEngine, a fully executable pure-Python pipeline for data-dependent acquisition (DDA) shotgun proteomics analysis. ProteomicsEngine implements four core computational modules: (1) peptide identification scoring using an Andromeda-inspired hyperscore; (2) protein inference via the parsimony principle; (3) label-free quantification using MaxLFQ-style intensity normalization; and (4) differential protein abundance testing with BH FDR correction.
