Dear Joe, Sorry for the confusion. I am working with martini force field and I have three different molecules in the micelle structure. I want to analyze the RDF of the constituent molecules with respect to the line that pass through the center along with its length. As I mention before this line

You cannot use a line as the reference. From a brief glance at the paper you link it seems like maybe you actually want to compute the expectation value of the micelle backbone, a method known as principle curves which is a generalization of principle component analysis. At any rate, you should

Well, since you are not interested in the duplex stability, I would not use -COM. See, during the simulation, the center-of-mass of such a small helix part can drastically move, leading to a questionable result. Check your system and make sure that you will not face this situation. About the PMF,
