Some of the rdfs go very abruptly to 1, so you might want to try: - increasing the cutoff - using a bigger system - doing a PBC correction as in http://dx.doi.org/10.1063/1.4742067
Another option is to - add extra exclusion - use a fudge factor for the 1-4 interactions - adding a couple of special 1-4 interactions for that I would split the rdfs in inter-molecular and intra-molecular pairs and check if the parts agree to the atomistic case separately.
