Hi All,
I am running Gromacs for drug enzyme complex using AMBER as
forcefield.While running pdb2gmx command I am getting error and warning of
790 missing atoms. Can anybody suggest me how to correct this error.
Either supply a structure file that has suitable hydrogens already built
in with some external program, or see what the problem is with the AMBER
.hdb file and your residues named CYSH. The required .hdb format is
described in Chapter 5 of the manual.
