[gmx-users] Ligand hybridization

[Chetan Puri]

I am confused with the fact that after processing ligand through prodrg
whatever pdb file you get it doesn't show aromatic ring double bonds( if we
view it using pymol or vmd)
And I don't understand that although it shows aromatic ring planar but no
double bonds are present.
So is it the way aromatic ring is supposed to be after passing through
prodrg.
