This module contains functions to calculate lipid order parameters.
This function calculates the order parameter for each successive triplet of atoms for each lipid over a trajectory. The order parameter is calculated from the angle between the director vectors between two successive pairs of atoms. Inputs: t : Trajectory lipids : EntityView containing the lipids to be analyzed aname_list: An ordered list of atom names. An order parameter is calculated for each successive triple of atoms
