[gmx-users] g_sas resarea.xvg

[Carla Jamous]

Hi everyone,

I used g_sas: g_sas -s .tpr -f .xtc -n .ndx -o .xvg -or resarea.xvg

What I don't understand is why there are 3 columns in the file resarea.xvg
although this is what's written in my file:
# g_sas is part of G R O M A C S:
#
# GROtesk MACabre and Sinister
#
@    title "Area per residue"
@    xaxis  label "Residue"
@    yaxis  label "Area (nm\S2\N)"
@TYPE xy

So I would expect this file to contain only two columns. I'm using gromacs
version 4.0.3.

Thanks for your help,
Carla
