Hi There,
I am usinng gromacs for running MDS of one protein, Can I use the pdb
file only without generating the .gro file i.e. without using pdb2gmx ?
Theoretically, yes. Gromacs can read a number of file formats at any stage
(.pdb, .gro, etc).
If no, then how can I avoid addition of hydrogen during pdb2gmx ?
Then you will probably have a broken (and useless) topology. Addition of
hydrogens is dependent upon the force field you want to use. All atomistic
force fields distributed with Gromacs require at least the inclusion of polar
hydrogens.
