The antechamber program (in version 7) can help you create your own
tutorials to study (or to avoid having to learn the details of resp
input at all.....).

Try this:

    antechamber -i name.pdb -fi pdb -o -fo gcart

will create "" that can be fed to Gaussian, e.g.

    g98 < > name.log

Now, you can use antechamber to automatically run the first and second
stage RESP:

    antechamber -i name.log -fi gout -o name.prepi -fo prepi \
          -c resp -s 2

This will create the required resp input files for your molecule (they
will be called ANTECHAMBER_RESP1.IN and ANTECHAMBER_RESP2.IN), and you
can study the output files as well (ANTECHAMBER_RESP1.OUT and
ANTECHAMBER_RESP2.OUT). The resp charges will end up in the "name.prepi"
file, which can be loaded into LEaP.

...hope this helps....dac
