The above is not an error from ptraj, but likely sander and states that
the file "1jkmpro3.xyz" could not be opened. Perhaps that file already
exists (zero sized) or write permission is not granted?

ptraj will only complain like this is the file actually does not exist.
Do a "ls" in your current directory and see if 1jkmpro3.crd is actually
there (or type "head 1jkmpro3.crd").

Good luck.
