[gmx-users] forces from trajectory

[Sikandar Mashayak]

Hi

In the post-processing ( analysis) code using gromacs trajectory, I access
force values on atom using fr.x[indx_atm][XX]. The confusion I have is that
" what force is it? is it the force before constraints ( fixed bonds) are
applied or is it the effective force due to atom-atom interactions plus any
constraints?"

thanks
sikandar
