[gmx-users] problems with rerun

2009-08-24 Thread rsf
Hi I have a molecule described by two sets of parameters (in atom connectivity and coupe values of bond interactions) and I need to get the energy difference between those two descriptions. I have been having problems with the rerun capability (I am using the latest version of gromacs) I did the

Hi I want to describe a reaction for what I have a system described by two different connectivities and need to run an MD calculation on a mapping potential of the type V1- C (V2-V1), where V1 and V2 are my diagonal elements of the evb matrix and C is a parameter. Does gromacs have support for run

Hi I have a silly question about the implementation of the Gromos forcefield in gromacs, particularly about the exclusions. I have the gromos manual and have seen that, for instance, for the residue MET there are only 1st and 2nd neighbors exclusions defined for it. However, when I build a protei
