Dear Gromacs Users,
I want to calculate the rmsd between two ligands - the system is exactly
the same, just the ligand binding conformations are different.
Therefore i want to use g_rms with the option -f2 as in the following
g_rms -f trajout.trr -f2 ../2/trajout.trr -n -o
In g_rms -h it says that this "generates a comparison matrix of one
trajectory versus the other" but I don't get this matrix.
Only the "normal" rmsd.xvg but it seems as it is calculated to the starting
snapshot and the f2-trajectory file is not considered.
Could anyone explain me how I execute this command correctly?
Thanks and best regards!
