You will need to do a little hand-editing. The charges and atom types for
a urea molecule are in the first eight atom records of the
file. You could use these to create a mol2 format file and read that into

Alternatively, you could probably load the file into xleap,
then use the unit editor to erase everything but one urea molecule, and
save that as a new unit.
