[gmx-users] leapfrog does not yet support Nose-Hoover chains

[Mark Abraham]

Hi,

Protein chains and NH chains are entirely different things (see manual for
latter). Probably for ligand-protein simulations the difference between NH
with 1 chain and more is marginal, and probably smaller than your sampling
error. You could a) use md-vv to get NH chains (but slower when run in
parallel), b) use v-rescale thermostat, c) change nothing and hope for the
best.
