Generically, you need to use "loadAmberPrep" to get the prep files read in.
You can use the "list" command to see that which residues are available; these
names need to match those in your pdb file.

You also need to use "loadAmberParams" to load in the parameter files, so that
the force field parameters needed by the residues in the sugars will be
available.

Sander doesn't know or care about what force field you are using. If you
can make the prmtop file succesfully in LEaP, then sander will get all it
needs to know from that.

..good luck..dac
