If I understand you correctly, this is straightforward. If you're scanning against our PDB95 database, for example, all the templates are single chain, and the chain ID is simply the last character in the align code.

If you're trying to align against a multi-chain template (presumably a local alignment) you could extract the chain ID trivially from the alignment object.
