Hi, That thermostat is really nice and also simple to implement. It is now in CVS. Thanks for the tip! Berk. > Date: Wed, 23 Jul 2008 10:12:36 -0400 > From: [EMAIL PROTECTED] > To: gmx-users@gromacs.org > Subject: [gmx-users] Re: Question about Berendsen thermostat and Nose-Hoo

Note that a recently a velocity rescaling algorithm was developed in the Parrinello group that does give the correct canonical ensemble. See: http://arxiv.org/abs/0803.4060. It might be nice to replace Berendsen with this algorithm, which should have the nice properties of Berendsen (converges to
