take a look at the ptraj part of the manual- what it wants after the ptraj
exe is the name of the prmtop. you gave it trajin, so it thinks that is
a file it should load. the trajin is a command to be given later.
it might help to go through the tutorials, I think the DNA one gives some
nice sample ptraj scripts that will be a better place to start.
good luck
