+There is one network for each species and kind of interaction, named as `<kind>_<species>` (e.g. `ppi_human` or `genetic_interolog_fly`), with the kinds `ppi`, `ppi_interolog`, `genetic` and `genetic_interolog` (there is no genetic network for the western clawed frog, and no genetic interolog network for the fission yeast). Nodes are genes (or the proteins they encode), identified by their NCBI Entrez Gene IDs, and an undirected edge connects two genes for which MIST lists an interaction of the given kind; when the same pair is listed in several records, only one of them is kept. The files of a species also contain some interactions with genes of other species (e.g. about 8% of the records of the human PPI file), which are included. The interolog files of a species contain both the interactions predicted for its genes and those predicted for the genes of other species (including Xenopus laevis) from its data, and all of them are included. The species of each gene is given by the vertex property `tax_id` (NCBI Taxonomy ID).
