Hisat2-build建立转录组索引
WebbIntroduction. HISAT2 is a fast and sensitive alignment program for mapping next-generation sequencing reads (both DNA and RNA) to a population of human genomes (as well as to a single reference genome). Based on an extension of BWT for graphs [Sirén et al. 2014], we designed and implemented a graph FM index (GFM), an original approach … WebbHISAT2 can incorporate exons and splice sites into the index file for alignment. First create a splice site file, then an exon file. Finally make the aligner FM index. To learn more about how the HISAT2 indexing strategy is distinct from other next gen aligners refer to the HISAT publication.
