RC454 (ReadClean454) is a program that takes a set of 454 read and quality files as well as a consensus assembly for those reads and corrects for known 454 error modes such as homopolymer indels and carry forward/incomplete extension (CAFIE). It will also correct for any indel that breaks the reading frame, unless it occurs in more than 25% of the reads. Since the algorithm is aggressive in correcting for errors, it is important to align the reads to their own assembly rather than to an external reference to prevent misalignments as much as possible. RC454 uses Mosaik to align the corrected reads between each step, and as such it is required to run the script.
