Hello Gromacs Users,

I have a 60ns trr trajectory file (converted with VMD from namd2
trajectory) which has 6000 snapshots saved at 10 ps intervals.  how do
I specify the snapshot interval to g_msd so it calculates the D
properly?


Which option are you referring to? The only one I can think of is -trestart, which has nothing to do with frame interval, but is related to statistics. You shouldn't have to tell any of the Gromacs tools what the frame interval is; if you have a valid trajectory, that information is already present.
