Hi Everyone,
   I am running galaxy locally (ubuntu 11.04) and I am having problem with samtools. When I am running TopHat I get an error message saying that could not locate samtools. Of course I did everything described in http://wiki.g2.bx.psu.edu/Admin/NGS%20Local%20Setup
 Here is the error message:
Error in tophat:

Error locating program: samtools

When I run "make" in the samtools directory I also get an error message:

koala2@aedes:~/Desktop/galaxy/samtools$ make

I also followed the installation guide from samtools, but did not work either.

Unfortunately I found myself spending more time installing tools than using it. Yes I am a newbie.
Thank you.
