What you describe should work, and you might have to put debugging information
into the reduce code to see why it is not doing what you expect.
However: if you already have a mol2 file with hydrogens, you can use tleap
to add hydrogens, bypassing the reduce step. Just load the mol2 file,
and a pdb file (missing hydrogens), and the output pdb file will have the
hydrogens added in their canonical positions.
...good luck...dac
