Subject: AMBER: bad atom type errors in GB for halides?

All,

This is probably naive, but I'm trying to run some simulations of
various small molecules in GB solvent. This includes some things like
bromomethane, etc. I can set them up fine with tleap (no
warnings/errors), but when I go to run in GB solvent, I get an error
like "bad atom type: br". Vacuum works fine, so I assume this is an
issue with GB parameters for these? This is with igb=5. Would I need
to derive my own parameters for these, or are there other options?
What would I need to edit and provide in order for this to work OK?

Thanks,
David
