[gmx-users] Error with g_angle: VERSION 3.3.2

[Sergio]

Hi all

I am trying to use g_angle tool to anayze a group of dihedrals but it 
gave a error that I don't understand. Could anyone tell me the origin of 
this error?
and How I can solve it.
This is the command line I have used: g_angle -f run_1.xtc -s run_1.tpr 
-all -n index_dih -ov dih_1 -type dihedral
Here below I have pasted the end of the output....

Group     0 (r_1-128_&_C13_C32_O33_C34) has   512 elements
There is one group in the index
ftp2fn: No filetype .???
