[gmx-users] g_angle

[hugo verli]

I've tried to use g_angle and I received the following message:

Fatal error: Can only do transition, fraction or correlation
on dihedrals. Select -d

I used the following options:

g_angle  -f md.trr -s md.tpr -n dihedral.ndx -ot -oh -oc

My compound is not a peptide. Could it be the reason of the problem or I made
something wrong in the use of the program?

Thanks in advance for any help,

Hugo Verli.
