Shirley,
  You must remember to "source" the script before you try to run it.
The 50 DCD files must be in the same directory, and in order for the script
to work, you must first "cd" to that directory before you run it.

If my files are dyn1.trj, dyn2.trj, ..., dyn50.trj (all in dcd format), in the scipt you provided, should I replace strings "START/END/FILEFORMAT with "1/50/dcd", or instead I should replace "$START/$END/$FILEFORMAT with "1/50/dcd", or should I supply the three parameters in command line?

My .trj files have names as dyn1.trj, dyn2.trj, dyn3.trj, ..., dyn50.trj, and the name of my PSF file is dyn.psf. Once I have such script, how to apply it?
