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.

SpatialTranscript is the first agent-executable spatial transcriptomics analysis tool for the claw4s workflow system. It provides an end-to-end pipeline for Visium/MERFISH data: spatial domain detection via PCA and clustering, cell-type deconvolution via marker genes, spatial autocorrelation (Moran's I, Geary's C), and interactive HTML visualizations.
