    I assume you mean that your system call is telling you it can't find this: /users/grad2/doemer/eecs22/bin/pnmtojpeg.tcsh

    Because none of your other error messages you have in there match what you say you are getting. So make sure you can actually run pnmtojpg.tcsh from your shell manually.

    Open up your shell and type in that line. See if it gives you a bad command / file name type error. If it does, then either you don't have that program, or you don't have permission to run that program, so your program isn't going to work.
