Dear Amber users,
I have been trying to process a molecular dynamics crd file using ptraj to
center the solute within the box after the dynamics run. The problem is
that ptraj does not seem to like g-zipped files (.gz extension). Here is
the input file:
trajin pme2_prod.crd
trajout pme2_centered.traj
center
image
go
..and the error from the output:
PTRAJ: trajin pme2_prod.crd
Could not open file (pme2_prod.crd) with mode (r)
WARNING in checkCoordinates(): Could not open file (pme2_prod.crd)
WARNING in ptrajSetupIO(): trajin pme2_prod.crd, cannot open file...
A similar error occurs if I try to use a .gz file; the program says
"Could not open file (pme2_prod.crd.Z)". Does ptraj expect conventionally
compressed files (.Z)?
Thanks for any help.
Sincerely,
