Hi Josh, There are two ways to do this. The simplest is to place the binaries into a directory on the Galaxy user's $PATH. The second is via the tool dependency system, which I need to write up documentation for to put in the wiki, which I'll do this week. > Even if that is the case though, I have occasionally gotten errors about > tools missing in completely different directories.

The list of external dependencies by tool is maintained here: http://wiki.g2.bx.psu.edu/Admin/Tools/Tool%20Dependencies I'll update this page with links to the new documentation when I write it. I should also add that work is under way to make it possible to automatically install these dependencies as needed. --nate > > Thanks, > Josh > ___________________________________________________________ > Please keep all replies on the list by using "reply all" > in your mail client.
