Hi all:
I prepare biguanide ligand for MD using antechamber with a command "antechamber -i xx.pdb -fi pdb -o xx.mol2 -fo mol2 -c bcc".
I have a question about atom type for N(highlighted in red) on conjugated chain, which were assigned to nh(N connected to aromatic ring in gaff). However, there is no aromatic ring(even a ring ) in molecular structure or file generated by antechamber.I wonder whether it is needed to modification or correction for this atomtype ? Thank in advance !
Best regard
R2 N N
