Hello,
After the latest update of Galaxy I saw that the cuffdiff wrapper is for version 2.0. I updated the $PATH to cuffdiff v. 2.0.2 but when I run cuffdiff in Galaxy I get the following error:
Error running cuffdiff. cuffdiff: /lib64/libz.so.1: no version information available (required by cuffdiff)
cuffdiff: unrecognized option '--library-norm-method'
cuffdiff v1.3.0 (3022)
 
What else do I need to define inorder to run the latest version of cuffdiff.

This depends on your setup. If you're running Galaxy under a particular user, you may have to update that user's $PATH. If you're running on a cluster, you'll need to ensure that the submission script uses the correct $PATH.

If you provide more details on your set up, it may be possible to provide additional insight/suggestions for your problem.

Best,
J.
