Re: [AMBER] Antechamber Segmentation fault (core dumped)

Hello Sir,

I am trying to run MD for a docked complex, the ligand is pretty big
which contains a hydroxymethylconduritol unit and a
4-amino-4-deoxy-D-chinovose residue linked to number (8-12) of
a-D-glucose units.

i was able to run antechamber for some small molecules successfully, but
i struck with this molecule.

please give me a brief idea to break and build the molecule or otherwise
how to incorporate glycam force field in to Amber or any other way to go
about it.

Thanking you.
