Another thing is i installed in a user so whenever i do project it gives permission denied .

I suspect you have the following situation: drwx------ 2 rwgk cci 4096 Mar 14 10:47 phenix-1.1a I.e. when you installed phenix the "umask" was set such that "group" and/or "others" don't have read permission. Please verify my suspicion with ls -d $PHENIX If you see the "drwx------" or maybe "drwxr-x---" it is easy to fix. Use the su command to become root, then: find phenix-1.1a -exec chmod go+r {} \; find phenix-1.1a -type d -exec chmod go+x {} \; Cheers, Ralf
