Dear Neelanjana,
Do you have gromacs installed on this machine? I suspect your paths are set
in such a way that you are not running what you think you are running.
Try
which protonate
which PROTON_INFO
If you try the following it will likely work:
$AMBERHOME/exe/protonate -d $AMBERHOME/dat/PROTON_INFO <peptide.pdb >
peptide2.pdb
Also take a look at peptide.pdb and see if it looks to be a valid pdb file -
I.e. one that adheres to the PDB standard.
All the best
Ross

Subject: AMBER: Error in protonating
Dear Amber users,
In protonating a peptide (coordinates available in pdb format), I use the
foll. command:
protonate -d PROTON_INFO < peptide.pdb > peptide2.pdb
and, I get the foll. error:
:-) G R O M A C S (-:
Segmentation fault
The peptide2.pdb does get created, but is a blank file. Could someone point
out what's missing here? I am using amber7.
Thanks,
--
