I have list of functional proteins of S.aureus strains from PGAAP pipeline and RAST server. I want to know how to find common proteins from these list. Can anyone suggest me which tool holds good for this job.
I would suggest BioVinci if you're still looking for the tool. The Venn diagram there is interactive and proportional. I believe it can create a Venn diagram for up to 8 groups. Plus you just need to drag and drop your data to create and customize your plot, which is quite quick and easy. (find it here: vinci.bioturing.com)

But as Alex has pointed out, there are a lot.
