Re: [gmx-users] Why h_bond can not form

I'm so glad to tell that the question seemed to be solved after I refine the charge of Zn atom and the atoms around it. +2 may be too much for the Zn atom, and reduce the positive charge according to the results of resp calculation. Also I think the simulation could be further refined after cha

It's so kind of you to answer my question in such a short time. I'll try other forcefields. Thank you very much! 在 2015-05-11 19:46:27,Justin Lemkul 写道: > > >On 5/10/15 8:48 PM, 范聪 wrote: >> Hello everyone! >> >> I offered a picture called "ask.png" to illistrate my question. >> >> According to

Hello everyone! I offered a picture called "ask.png" to illistrate my question. According to the referense papers, the H atom of the -OH group of TYR306 should form H_bond with the carbonyl O atom of the ligand. But in my simulations, the H atom turned after a very short time, towards the sid
