I just want to do a Comparative analysis of orthologous protein groups of three species. I thought to use OrthoVenn for the pupose. But when I submit some error is showing. I tried with fasta file downloaded from the Uniprot, also tried with the inbuilt species in OrthoVenn. But the same error pops out. Is the website is down?? Are there any other tools for this purpose? Thank you for your answers.
