Hi all,

I've just been trying to prepare a protein for setting up a docking
with Autodock. Is this pdbqt format intended for this or is it just
for the ligands? The description in the help message is somewhat
minimal.

In any case, I tried to do this conversion but after several minutes
waiting I terminated it and filed a bug:
https://sourceforge.net/tracker/?func=detail&aid=3167053&group_id=40728&atid=428740.

Am I doing something wrong?
