[gmx-users] memory error

but in the output I see this message: "number of CPUs for gaussian = 1 memory for gaussian = 5000" and then I get a memory error. I don't see any description of keywords in the manual to set the memory in the mdp file, but maybe I'm missing something. Does anybody have a

e (you'll have to dig into the literature, maybe you can find solvated structures or a radial distribution function) and then adjusting the parameters until the experimental value is reproduced. You could also benchmark the molecular mechanics parameters against a higher-level qm computation by

ded a gaussian keyword to allow the gaussian computation steps to tolerate close interatomic distances.
