Self-similarity at corners. Dotplots of the same encoded DNA, showing only the ends of the sequence, generated with word size 10. Short blocks of repetitive sequence are visible as blue blocks, these result from header and terminator information utilized by the LZMA algorithm which is less variable than the compressed data stream itself. Top left: Sequence head vs. itself. Top right and bottom left: Head vs. tail. Bottom right: Sequence tail vs. itself
