If you use the "desc" command to examine your residue, you will find that
Amber is using IUPAC names for the sugar atoms, (that is O2') rather than
Brookhaven/PDB names (like O2*). So, use the Amber/IUPAC name.
[If you examine files like leaprc.ff99, you will see that LEaP is converting
the names found in pdb files to its internal standards. Other programs, like
ambpdb, reverse this change on output.]
...good luck...dac
