Blocks of database residues processed together. The residues of the first five vectors processed are indicated on grey, blue, red, green and yellow background. Four symbols from each of the database sequences form blocks that are processed as a group. Padding of some sequence blocks are indicated with dashes on a pink background. An additional database sequence change is indicated with a pink vertical bar. Arrows below the sequences indicate positions were new sequences begin.
