Thank you very much, Jason.

I have another cpptraj-related question. I'm using this input:

parm rat.parm7
trajin rat.001 remdtraj remdtrajtemp 7.00
autoimage
atominfo :1-2991 out atominfo_7.dat
trajout rat_7.pdb

Why cpptraj is not producing the atominfo_7.dat file? I only have the print
on the screen.
