[gmx-users] g_bundle

[Senthil Kandasamy]

Just thinking out loud and wanted to make sure I was interpreting this
correctly. I am interested in finding the angle, an alpha helix forms
with respect to the membrane normal (Z-axis )in  a membrane simulation.
So, I used g_bundle with the -z option and set "-na 1". I specified the
two groups to be the C-alpha of the first and the last amino acids.
Then, bun_tilt.xvg should show the approximate angle that the helix
forms with the z axis. I think I am correct...Just need some
corroboration as a confidence booster...

Thanks.
