[gmx-users] g_bundle issue
Hi ALL, I tried to calculate the helix tilt of a single helix (TM5) among 7 helices using g_bundle. In the index file I defined the two groups (top bottom) as the C-alpha of the first 5 and last 5 residues of TM5 respectively. But in the bun_tilt.xvg file I am getting the values as: --- # This file was created Thu May 20 15:29:50 2010 # by the following command: # g_bundle -f prot.xtc -s prot.tpr -n TM5_top_bot.ndx -na 1 # # g_bundle is part of G R O M A C S: # # GRowing Old MAkes el Chrono Sweat # @title Axis tilts @xaxis label Time (ps) @yaxis label (degrees) @TYPE xy 0 0 2 0.0197823 4 0 6 0.0197823 8 0 10 0 12 0.0197823 14 0 16 0.0197823 18 0 20 0.0279765 22 0 24 0 26 0.0197823 28 0 30 0 32 0 34 0 36 0 38 0.0197823 And when plotted it gives a blank plot.

Re: [gmx-users] g_bundle issue
Have you tried using the -z option to calculate the angle with respect to to the z axis? I vaguely remember having an issue like this a few years ago and this fixed the problem, sorry I can't be more specific.
