xlsx file with 3 tabs: Catalogs, Collectors Curves, Venn Diagram, and Robinson–Foulds.

The Catalogs tab has the EukProt Species IDs and whether a homolog was found (1 = found homolog, 0 = did not find homolog), for each protein family. This tab makes up the raw data from which Figs 1B and S2 were generated. The Collectors Curves tab has the raw data used to make the graphs for S1B Fig. The number of search hits for each specified search is enumerated for each protein family. Searches that were not carried out are blank. The Venn Diagram tab has the EukProt Species ID against the presence/absence of a given homolog in Metazoa and non-metazoans (1 = found homolog, 0 = did not find homolog). The Robinson–Foulds tab has the raw data for each pairwise comparison between the various phylogenetic trees. (XLSX)
