I was trying to calculate diffusion of water molecule in a membrane
channel protein by g_msd utility of gromacs.
First I have identified channel waters which reside inside the channel
for 500ps (5000ps-5500ps simulation time).
Letter I have made a index file specifying these water molecules.
my input command was g_msd -f XXX.xtc -s XXX.tpr -n index.ndx -o msd.xvg
-type z -trestart 20 -b 5001 -e 5500
My question it is the correct way to calculate the diffusion for my
desired water molecule within desired time?
