Description

Blast results have lower case chains reported as a doubling of the upper-case chain letter (i.e. chain 'q' is reported as 'QQ' in the results). Therefore the resulting matchmaker command is wrong (e.g. "matchmaker #2/QQ to #1/C" should be "matchmaker #2/q to #1/C")

An example is blasting 5an9 chain C. The first non-5an9 result is 4w22_QQ.

Fixed in 4c653742c.

Blast database for PDB from NCBI uses funky doubled+capitalized identifiers instead of lower-case chain ids. The actual chain id is in the description, so we fetch it from there instead.
