Having a deoxy in the sequence triggers a deletion, so in DGlcp[3Me,4D] the 4D gets parsed by the sequence parser as a derivative, but in the 3D structure it just triggers an atom deletion then disappears. Except I forgot to update the atom numbering and residue numbering so they would skip numbers in the output, and the 3Me would be residue number 6.
