tfscan

[Michael Black]

It was my understanding that as of a year or so ago (or two now ? I 
can't remember when the notice came out), there is no such thing as a 
freely downloadable TRANSFAC database.  If you want the latest version, 
you must pay for it, through BioBase Corporation or their US 
distributors, Cognia Corp.  Of course, there are free web portals to 
BioBase's products (www.gene-regulation.com), just no free downloads 
for local use.

If I'm wrong, someone will hopefully post a URL or FTP address, but I 
remember getting an email a long time ago from BioBase, when they took 
over the database, that it would no longer be freely distributed.

Cheers, Michael
