<div><br></div><div><br></div>Dear Emma<div><br></div><div>The hills in WT_MTD are defined in a different way and to reconstruct the potential the inverse of delta_t is needed. </div><div>In a standard MTD this parameter is not used. Hence, the potential that has been already generated cannot be correctly taken into account in a MTD run restarting from WT_MTD. </div><div>It should be easier to keep on running with WT_MTD but attenuating the effects of the temperature on the hills' size.</div><div><br></div><div>Regards</div><div>Marcella<br><br></div><div class="gmail_quote"><div dir="auto" class="gmail_attr">On Friday, November 18, 2022 at 4:28:42 PM UTC+1 emma.r...@studenti.unipd.it wrote:<br/></div><blockquote class="gmail_quote" style="margin: 0 0 0 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">Dear all,<div>I performed a well tempered metadynamics (WT-MTD), but my sampling is too poor.
