Type with Consensus Refinement
The Type with Consensus Refinement tool is inspired by the Iterative Refinement Meta-Assembler (IRMA) tool [Shepard et al., 2016] developed by the Center for Disease Control and Prevention (CDC) in the USA. The primary use for this tool is to assist in the typing of small, segmented viral genomes such as Influenza viruses. The tool works by iteratively mapping the reads to a set of annotated reference sequences, evaluating the quality of the mappings, and extracting consensus sequences. This process is repeated using the consensus sequences as new references until the mapping metrics stabilize, indicating that further iterations will not improve the results.
After finishing the iterative refinement process, the tool transfers all annotations from the references to the consensus sequences. The CDS annotations are translated into protein sequences. These sequences are then checked for unexpected codons at the start and stop positions as well as unexpected internal stop codons that may indicate frameshifts in the consensus.
