Hi all, Stochastic dynamics is described in section 3.8 of the Manual (v. 4.5) Equation 3.108 is dimensionally incorrect, or at least I cannot understand it. Left hand side is a force, and the first term on the right hand side has a missing length in the numerator to be a force. This is accor

Dear all: I'm running a test case defining all the interaction parameters in the topol.top file. My system consist of two NH3 molecules. Every thing goes well except for the role played by the "cgnr" values: Depending on how I assign these numbers the calculated Coulombic interaction changes. If I
