From: Browsing repeats in genomes: Pygram and an application to non-coding region analysis
Pygram of the 8 kb CRISPR from Methanothermobacter thermautotrophicus str. Delta H (RefSeq entry NC_000916). The picture shows a log-pygram representing all repeats with 20 nucleotides or more, identified on both strands of the genome. Arrows point out the corresponding parts of the 5 internal duplications, while the horizontal curly parenthesis highlights the overlap of three out of five internal duplications. The bottom line of the pygram displays the location of the full CRISPR (yellow rectangle) and its repeated units (grey rectangles).
