Hello all,

I am trying to get a single point energy and force calculation in the
format listed earlier.

This input file

http://code.google.com/p/pbsa/source/browse/trunk/BSD/debug.f?spec=svn105&r=105and
does not appear in the AMBER11 manual.

How can I re-write the input file to get rid of this error? I apologize
ahead of time if this is an obvious error. I've checked the obvious
sources and can't find further information.

thanks in advance!
