Conditional Orthology Assignment

The conditional orthology assignment method is a “one click” program for identifying homologous transcripts from a whole de novo transcriptome assembly.

Depending on transcriptome size conditional orthology assignment may take several hours. Your email address is not stored or recorded and is used only to provide you with a link to the results once assignment is complete.
