I noticed that eggNOG has updated to version 4.5. I downloaded their NOG.members.tsv from the ftp. And all the sudden, there are these "ENOG" numbers everywhere, examples:
ENOG41118X1 ENOG4111BGB ENOG410YBUW
It seems that the COG classification loves to create new categories, from COG to KOG to NOG and now to ENOG.
I would like to ask, does anybody have an idea, what are these new ENOGs numbers? I search several of them in eggNOG, the returning results bear no difference with their COG counterparts. So any hints are appreciated.
Also, I have old COG annotations from http://www.string-db.org. There are still NOG numbers in them. If I search NOG numbers now in eggNOG 4.5, (for example: NOG18999), it will say no results. So how can I convert the old NOG number to the newer COG/ENOG system please? Thanks!
