PASSion uses the mapped read in a pair as anchor and then uses a high resolution algorithm, pattern growth, to remap the proximal and distal fragments of the unmapped read to a local region of the reference indicated by the mate. It is capable of identifying both known and novel canonical and non-canonical junctions with SNP or sequencing error tolerance.

ART is a set of simulation tools to generate synthetic next-generation sequencing reads. ART simulates sequencing reads by mimicking real sequencing process with empirical error models or quality profiles summarized from large recalibrated sequencing data. ART can also simulate reads using user own read error model or quality profiles.
