[gmx-users] Multiple parameter entries in itp with the same name

[Andrew DeYoung]

Hi,

If I have a force field parameter file (for example, ffnonbonded.itp) with
multiple entries with the same name (for example, multiple [ atomtypes ]
entries with the name "CA"), which one is used by grompp: the first one or
the last one?

My guess is that the last one listed is used, but I guess I can do a gmxdump
of the .tpr file to find out for sure.

Thanks so much for your time.
