Figure 3From: Genome-scale NCRNA homology search using a Hamming distance-based filtration strategyThe framework of genome-scale ncRNA search using HD seeds. In the first step, HD seed hits (represented by diagonal lines) are identified. Then more sensitive local structural alignment tools such as FOLDALIGN and PLAST-ncRNA are applied in the region surrounding a seed hit. Subsequent analyisis can be conducted on the output of the second stage.Back to article page
