[gmx-users] How to use ambconv

[Bob Johnson]

Hello everyone,
Is there anything special you have to do when using ambconv? I downloaded this
program today from the Gromacs website and am having problems with it. I'm
trying to convert topology and coordinates generated using Amber7. I give the
following command:

ambconv -at amber.atop -gt gromacs.top -rst amber.rst -gro gromacs.gro -pdb
gromacs.pdb

I get the following message:
AMBER .top               : amber.atop
GROMACS .top             : gromacs.top
AMBER .rst               : amber.rst
GROMACS .gro             : gromacs.gro
PDB .pdb                 : gromacs.pdb
Segmentation fault

Does anyone know how to use this?
Thanks,
Bob Johnson
