[gmx-users] Choose groups for force output

>From an/during an MD simulation of a protein in water or urea solvent I
would like to extract the forces acting on certain protein atoms from the
whole solvent (that is, one protein atom but all solvent) at for example
every 10th timestep.
With nstfout I can set the frequency for output but how can I choose to
output only some of the forces? How to remove the protein intramolecular
forces from the protein solvent forces? How to choose only some protein
If it is more convenient, perhaps there is a possibility to re-calculate the
forces based on the trajectory file?
