Other methods for fast indexing also emerged at this time, such as the BLAT [50] and SSAHA [93] programs, both of which (similarly to FASTA) used a hash index based on ktuples. ...
To solve this complex, high-dimensional puzzle, reads must be mapped back to a reference genome to determine their origin Due to sequencing errors and to genuine differences between the reference genome ...
These seeds can be matched efficiently using a structure like the FM-index and guide a coarse alignment method [19] developed for the alignment of whole genomes. ...
