Hi,<br><br>Indeed v-rescale did not work with md-vv and md-vv-avek.<br>I have fixed it for the next beta release.<br><br>Thanks for reporting this,<br><br>Berk<br><br><hr id="stopSpelling">From: mark.abraham@anu.edu.au<br>To: sht_ycw79@hotmail.com; gmx-users@gromacs.org<br>Date: Tue, 3 Aug 2010 13:21:37 +1000<br>Subject: Re: [gmx-users] md-vv and md-vv-avek with velocity-rescaling        thermostat<br>CC: <br><br>The simplest explanation for your observations is that you were not running the ensembles you think you were running.
