[gmx-users] g_helixorient

[Javier Romero Garcia]

Hi, have you tried to see the graphic with xmgrace using the flag "-nxy"? I had the same problem my first time.

Best regards.

Hi,

I have a peptide inserted in membrane would like to analyze the peptide tilt.

The command i have used to do this is :

g_helixorient  -s .tpr  -f .xtc  -n .ndx  -otilt

Index file contains all carbon alpha atoms of the helix.

When i plot the tilt.xvg in xmgrace,  i simply cannot obtain anything more than zero line graphic.

My tilt.xvg file contains:
