Hello,
When I use pdb2gmx, the bonds between atoms in the generated conf.gro or conf. pdb file are
misplaced. I am using Avogadro for building the atomistic structure, it uses "connect"
command to connect atom correctly. After running pdb2gmx, the generated files do not have
"connect" and they put the bonds is some random places. An suggestion for solving this
problem or any other software for building structure without having this problem?
The only bonds assigned are what you specify in the .rtp file. If it's not
right, fix the .rtp.
If I just want to consider bond stretching in my analysis, what should I do to
tell gromacs neglect angle,improper, and dihedral? I received 89 errors for not
defining them.
You'd remove them from the topology entirely. That will be a seriously flawed
physical model, unlikely to produce any useful results.
