Re:Re: [gmx-users] remd with different potential at different temperature

dear teacher, if i want to do remd with different tabulated potentials. how can i use the mdrun's -table (-table table.xvg -tableb table.xvg )? if it can also use like that,there is another question: and how can i rename the tables name ( table_CR1_CR1: i rename them table_CR1_CR10,table_CR1_CR1

Re: 回复： [gmx-users] Re 1. orca and qm/mm (xi zhao)

I am not sure I understand exactly what you mean but this is all covered in Gerrit's QM/MM tutorials, I'd recommend you go through those. In the ORCA files there is no need to do anything with LAs, GMX will hand a file with the QMsubsystem to ORCA which includes the LA as hydrogens in your case

Hi Alex Deuterium order parameter is a property related to the relative orientation of molecular axis taking the bilayer normal as reference. How to use them to extract useful structural information is a matter of how you interpret the values regarding their definition (see e.g. Egberts and B
