[gmx-users] Gauche dihedrals fraction

[Sławomir Stachura]

Hi,
I have simulated fully hydrated POPC membrane for 50 ns and now I am analysing if it's in equilibrated state. One of the needed by me parameters is fraction of gauche dihedrals in acyl chains.  I have tried g_angle, but it only shows fraction of trans dihedrals. So is there possibility to  calculate this parameter from trajectory? 
Best wishes,
      Slawomir
