NCBI Viral RefSeq Project

NCBI Virus RefSeqs The NCBI RefSeq project leverages the data submitted to the International Nucleotide Sequence Database Collaboration (INSDC) against a combination of computational, manual curation, and collaboration to produce a standard set of stable, non-redundant reference sequences. In general, only one complete RefSeq genome is created for each viral species. Occasionally multiple RefSeq records are created within a given viral species to reflect well defined genotypes or important laboratory and/or wild strains. Also, a separate RefSeq record is created for each segment in segmented viral genomes. Often the first genome submitted to INSDC databases is chosen as a RefSeq, but when possible, preference is given to sequences from strains or isolates of practical importance and/or well-annotated sequences.
