Respectable Experts I am very grateful to Justin. Yes I have defined the atom OB with its mass in the ffgmx.atp file. I have also defined the residue OMOL in ffgmx.rtp file that I am using.   Thank you         ___ gmx-users mailing list

Dear All, I just found that there is a problem when I extract the density of water from my Gromacs simulations. When I used g_density to get the water density from .trr trajectory file, the density plot looked normal. But when I used trjconv to convert the .trr to .gro file,
