Typical output from the GO-Family program. In this figure, we have asked for all the genes from human, mouse and nematode that share more than 45% functional similarity with an input gene: the Drosophila gene engrailed. The output is composed of four columns: rank, name of similar gene, percentage of similarity and species from which the similar gene is issued.
