Hi everyone,

I am trying to analyze dihedrals of molecules after a simulation. I am able to calculate dihedral distribution at ant particular time using g
-angle and proper group using

g_angle -f after_md.trr -b 800 -type dihedral -n chain1.ndx -od dihed12

This gives me the distribution at t=800 ps . What i really want is to see the dihedral distribution at all time steps (after 800 ps) in one go, and may be do some averaging later. Is there a straight forward way to do this. I can imagine that i could write a script file that could do this but then i dont want to deal with a lot of files, i rather want everything to be saved in a single file with multiple columns. Could someone suggest a trick for this?

The first paragraph of g_angle -h suggests there's an option where "the first graph is the average, the rest are the individual angles." Does this work?
