[gmx-users] Porphyrine-like molecule

[Alexander Borodin]

Dear gmx-users,

I'm going to simulate porphyrine like molecules.
Is there any way to keep them (~30 atoms per  molecule) strictly planar
using dummy atoms,
or I should define dihedrals?

Is some force-field for porphyrine or phthalocyanine implemented in Gromacs?

Thanks in advance,
Alexander
