Hi all

I am looking for a way to import forces from a gromacs run into VMD for analysis. From a mdrun –rerun I have forces in a .trr file but VMD only reads the coordinates. Can you think of any way to get the forces into vmd instead of the coordinates?

If VMD will only import positions from .trr files, then you could write a forces-only .trr file and through a code hack or hex edit, force the frame header to describe them as positions. Or, write a new VMD plugin. Or, modify the VMD source suitably.
