Hi gmx-users, Can anyone tell me how to find the total energy of the protein only (not the system)? You might try energygrp_excl SOL SOL or energygrp_excl SOL SOL SOL PROTEIN depending on what you want to acheive. THis will take care of all of the nonbonded interactions. Without knowing wha

Thanks Berk, everything is fine at last. I guess this is my last question : if for example I change three bond lengths from b0A=0.1 to b0B=0.15, when I use gmxcheck with -ab, it prints only one difference between state A and B, instead of 3. Is this ok ? Maik, what is the power you are using

Hi gmx-users, Can anyone tell me how to find the total energy of the protein only (not the system)? What I've done is I minimized the system first, then I took out the water from the pdb file, then minimized it again without water, and get the total energy from the log file. But when I'm comparin

Dear All, maybe anyone knows why I'm getting a 'segmentation fault' error while I'm running mdrun. I know that something is wrong with my mdp file, but do not know what exactly can cause it (what parameters I should do not use or use instead). Thank you in advance

Hi This warning is really strange. You could try to execute grompp with -pp to get the preprocessed topology and have a look, if the the B-parameters are included correctly. As far as I know, it should; I do it the same way. Anyway, you could also explicitly take the parameters for that dihedra
