[gmx-users] g_bundle problem

[Stefan Hoorman]

I have tried using g_bundle in order to analyse helix axes in my
transmembran helices. I created two groups in my ndx file that included the
alpha carbons of the first half of my helix and a second group for the alpha
carbons for the second half. When I try using g_bundle the following error
comes up:
"Fatal error:
The size of one of your index groups is not a multiple of n"
What am I doing wrong?
Thank you
