Re: [AMBER] Extracting forces from the mdcrd file

You could potentially use cpptraj. If you just want the forces from a
combined NetCDF file into a NetCDF file containing only forces:

trajin combined.nc
trajout forces.nc mdfrc

If you want them in ASCII format you can write to Amber ASCII
trajectory format by using the forces as coordinates:

trajin combined.nc usefrcascoords:
trajout forces.crd

Hope this helps,
