Embedding matrices reveal separation of features and samples and enrichment in certain metabolic pathways. a UMAP plots of sample embedding matrix W reveal some separation between batches and cancer types, as well as b separation between tumor and normal samples. c Feature embeddings separate peptides and lipids from other metabolites. d Certain pathways are enriched in certain embedding dimensions, though analysis is limited by statistical power
