Fig. 5. Comparisons of a subnetwork with matches to bile acids from 88 feces and gall bladder samples of various animals (MSV000084170).

This overview compares a the FBMN results to IIMN b before and c after collapsing all ion identity networks into single representative nodes. In the top row, nodes are colorized depending on the adduct that ion identities are based on. In contrast, the lower three networks emphasize nodes with MS² spectra that match library spectra of specific compound classes, mainly bile acids and their conjugates. The collapsed network (c) reduces the complexity and redundancy of having multiple nodes per compound and only keeps MS² spectral similarity edges.
