Dear All,
For the pdb2gmx, if I will not assign charges to the N-terminal residue and
C-terminal residue, I need to use pdb2gmx -ter, or I need to use pdb2gmx
-[no]ter?
The -ter option allows you to choose protonation state or no terminal processing
if there are caps.
In addition, whether there will be charges at the N-terminal residue and
C-terminal residue has relation with the force field used, am I right?
I don't understand this question. The individual partial charges on the atoms
are indeed a function of the force field, but the choice of protonation state or
capping is totally independent of the force field and is dictated by biological
relevance.
