[gmx-users] Error in calculating center of mass using distance command

[Sumedha Bhosale]

Hello,

I am trying to calculate the center of mass of residues 513-515 and 588-590
of chain A and chain B using distance command. I want output in histogram
format. But it seems that distance command is a calculating the distance of
my first group and itself. It's not taking the second group. I am getting
all values as zero in histogram plot.
I have made index files for two separate groups of chain A and chain B. I
am using the command - com of group 34 plus com of group 35.
I am attaching output file.
