Model 4 is SCWRL sidechain replacement for the alignment
T0225-1n2sA-t2k-local-str2+CB_burial_14_7-0.4+0.4-adpstyle5, using our
second-best-scoring template 1n2sA.

The best-scoring template (1r66A) was observed in PDB, but was not in
our template library, so we could only do sequence-based alignments to
it, which are not reported as models in the automatic method.
We did not think it worth the trouble to add 1r66A to our template
library, as the models we were getting looked good enough without the
full set of alignments for 1r66A.
