Thanks for quick answer!! Okay, the main criteria for convergence is to compare the distribution function one by one with target function
In my case, the Convergence sum is start from 15000 and after step 2, it varies from 3000~5000 in every step until more than 300 step when I compared the distribution function, the votca fits the specific peak on the target and switch the specific peaks to others again and again. is it normal process for votca? and, The peak location is similar but the y-value has absolute difference comparing to the target, is it OK?? In addtion, I wonder the votca has the potential fixed options which means that, Q. If the A-A rdf shows good convergence comparing to the target distribution, then can I fix the A-A non bonded CG parameter and continue the iteration for other non bonded interaction? (A-B, A-C ...etc)?? Since the iteration could be faster when we start from simple parameterization to complicated parameterization, is there any tips or advice for non bonded IBI instead of iteration for 6 nonbonded parameter at the same time. (for example, <do_potential> options etc....> Anyway, I really thank to develop votca^^ 2018년 10월 5일 금요일 오후 9시 17분 24초 UTC+9, Christoph Junghans 님의 말: > > On Fri, Oct 5, 2018 at 6:12 AM changseo park <parkch...@gmail.com > <javascript:>> wrote: > > > > TO.
