No, you're the first with a good explanation why this might be happening. Nobody's been game to say where they got the idea for their coupling schemes :-) Does someone with some clout wish to suggest to Kerrigan that he use ; Berendsen temperature coupling is on in three groups Tcoupl = berendsen tau_t = 0.1 0.1 tc_grps = protein non-protein ref_t = 300 300 in his tutorial? This actually simpler for him, rather than specifying different things when Cl is absent and present.
