g_pme_error - estimates the error of using PME with a given input file VERSION 4.6.5

g_pme_error estimates the error of the electrostatic forces if using the sPME algorithm. The flag -tune will determine the splitting parameter such that the error is equally distributed over the real and reciprocal space part. The part of the error that stems from self interaction of the particles is computationally demanding. However, a good a approximation is to just use a fraction of the particles for this term which can be indicated by the flag -self.
