Thanks for the suggestion Chris. Had a quick look and can't see easily how to do this, but I think I am at a point now where it is not an issue and don't have to actually do this. Catch ya, Dr. Dallas Warren Drug Delivery, Disposition and Dynamics Monash Institute of Pharmaceutical Sciences, M

I likely won't have much time to look at it tonight, but you can see exactly what the option is doing to the topology. run gmxdump on the tpr. All of the stuff that couple-intramol does is in grompp, so the results will show up in the detailed listings of the interactions, and which ones have whi

Michael, thanks for taking the time to comment and have a look. The real issue I am having is a bit deeper into the topic than that, my last reply was just an observation on something else. Will summarise what I have been doing etc. I have a molecule that are calculating the Gibbs energy of hy

Chris, Thank you, that appears to be the issue then. Running them again now with couple-intramol = yes Will report back once that is completed with the results. Catch ya, Dr. Dallas Warren Drug Delivery, Disposition and Dynamics Monash Institute of Pharmaceutical Sciences, Monash University 38

Chris, You are correct in the first part of your statement, part that isn't correct is I expect for the same charge on the atom I expect it to give the same dH/dl value. For example, for the OE atom that I provided the graphs for ( http://ozreef.org/stuff/octanol.gif and http://ozreef.org/stuf

Here is the molecule in octanol http://ozreef.org/stuff/octanol.gif And here in water http://ozreef.org/stuff/water.gif Just realised, it is actually quite different in water, consistently. So the only difference between the two simulations is the charges on the molecule have been multiplied by
