Usage:
swapna new_type atom-spec

Swapna "mutates" nucleic acid residues by replacing their base moieties. Every residue with at least one atom in atom-spec is changed to a new_type residue. New_type is a one-letter code representing one of the standard nucleic acid bases: A, T, G, C, or U (case is unimportant). The geometries of the new residues may not be optimal.

The temperature factor for the new residue is set to the highest currently found in the model.
