Justin, In a previous thread on core/shell optimization ( https://mailman-1.sys.kth.se/pipermail/gromacs.org_gmx-users/2014-August/091101.html) you state: "No, I've made wholesale changes to the code in the way that energies and forces are computed. The current code has bugs. If you want a

[gmx-users] name of the residue contact between two proteins

hi, i have two protein in a system.i have already calculate the no of contacts between two proteins. now i want to caculate the name of the residues which are in the contact within 5 angstrom of the two protein. i.e the name of residues of protein1 which are in the contact with the residue name of

So I take it then (and to confirm this) that it is an issue with the output from gmx bar to the histogram file, rather than results from the lambda state simulations? But the results it has presented in the results table and final value for the free energy change is "correct"? Previously I'd only

Hi, gmx bar got a last-minute rewrite before GROMACS 4.6 (some implementations of some of the free-energy algorithms changed) and I'm sure it's still in need of love. However, the core team can't do all the things we'd like to do, so if there are people who want to have working alternative

Dear All, I have a question regarding the make_edi tool. I used it some time back to restrain my structures to a particular projection value of an eigen vector with the -restrain keyword. However, I seem to have forgotten how to set the value of the projection in the .edi file. Does anyone here
