Example of dotmatch analysis in GenomeMatcher. (A) DNA regions of CRISPR [11] in Escherichia coli K12 MG1655 genome (U00096). MG1655 genome was placed both on x- and y axes. (B) Close-up view of panel A. Exact matches with sizes larger than 'word size 1' are shown in black and those larger than 'word size 2' in red. As in the main window, regions to be compared are easily be set by dragging or pressing the navigation buttons.
