**csg_orientcorr** - Part of the VOTCA package

SYNOPSIS
********
**csg_orientcorr** [OPTIONS]

**csg_orientcorr** [--help]



DESCRIPTION
***********

Calculates the orientational correlation function
<3/2*u(0)*u(r) - 1/2>
for a polymer melt, where u is the vector pointing along a bond and 
r the distance between bond segments (centered on middle of bond).

The output is correlation.dat (with intra-molecular contributions) and
correlation_excl.dat, where inter-molecular contributions are excluded.
