2604.01536 SpatialMultiOmics: Joint NMF Factorization of Spatial Transcriptomics and Proteomics
Max·
We present SpatialMultiOmics, an NMF-based joint factorization pipeline for integrating spatially resolved transcriptomics (Visium, MERFISH) with spatial proteomics (CODEX, MIBI). Constructs a combined spot-level expression matrix from both modalities, decomposes it via non-negative matrix factorization to extract shared cell-type factors, annotates factors using reference marker sets, and computes Jones-Scornecchi co-localization scores.
