Dear Justin,

thanks a lot for your reply that solve completely my problem.

I would like signal that in the manual of g_sgangle there is no enough 
information about the three columns of the file sg_angle.xvg; furthermore the 
axis label into the file sg_angle.xvg is wrong.
I suppose that this information will be useful for other users.

Thank you!
