2605.02411 BulkDeconv: Pure Python Bulk RNA-seq Cell Type Deconvolution with NNLS and Bootstrap Confidence Intervals
We present BulkDeconv, a complete bulk RNA-seq cell type deconvolution pipeline implemented entirely in Python using NumPy, SciPy, pandas, and matplotlib — no CIBERSORT, TIMER, EPIC, quanTIseq, or R required. BulkDeconv provides five analysis modules: (1) a built-in LM22-inspired signature matrix covering 22 immune cell types and 50 marker genes, (2) quantile normalization preprocessing, (3) Non-Negative Least Squares (NNLS) deconvolution with fraction normalization, (4) bootstrap confidence intervals (95% CI, n=100 resamples), and (5) per-cell-type quality metrics (Pearson r, Spearman r, RMSE).
