[gmx-users] Gromacs bug related to rms and atommass.dat interplay (Can not find mass in database for atom MG in residue)

2020-02-05 Thread Vedat Durmaz
Hi there, I'm pretty sure it's not a feature but a bug which I've faced in the GMX versions 2018.7, 2019.5 an 2020. When I try to calculate RMSD values for a protein system including a catalytic magnesium ion "Mg" using the command gmx rms -s mol.pdb -f mol.xtc -f2 mol.xtc -o mol-rmsd.xvg

Hi everybody, After 7 years I'm trying to do some implicit solvent simulations of protein-ligand systems again using Gromacs/Amber and running into the same issue as before: GB parameter(s) missing or negative for atom type 'N3' GB parameter(s) missing or negative for atom type 'H' GB

[gmx-users] (cross-)compiling mdrun independently from the rest of gromacs tools
