Example of GenomeMatcher analysis. Two sequences in the GenBank format are loaded and compared successively three times by bl2seq. Clicking the arrows besides the comparison image displays the text-based annotation information. (A) Clicking a stored image in the right image column converts it into a larger image. The black asterisks denote comparison ranges of the current image, and the red ones the ranges to be compared in the next analysis. (B) The representation of the comparison result of panel A in parallel view (parallel-flip-view, in which the upper sequence is flipped). See the instruction manual for more details.
