Re: TopoTools for tpr file

You are better off writing the topology file by hand or at least start
with pdb2gmx, which you can then edit to be consistent with your gromacs
parameter files and input coordinates.

To get the TPR file you need something like this:
grompp -f myfile.mdp -c myinputcoords.gro -p topol.top -o myinput.tpr

Where myfile.mdp is the file analogous to the NAMD simulation input file
that sets the temperature, timestep, etc.

As Alex mentioned, this is really a gromacs problem, so you should post
on their mailing list.
