Figure 3From: PILER-CR: Fast and accurate identification of CRISPR repeatsPile construction. When local alignments are projected onto the genome, "piles" are produced. A pile is a contiguous sequence of bases, each one of which has a hit to at least one other region in the genome. Bases that are not in a pile are unique sequence. Each local alignment connects two piles. In this figure, each hit has a different color so, for example, the purple hit connects the first and second pile.Back to article page
