To our users Please note that the HCV database site is no longer funded. We try to keep the database updated and the tools running, but unfortunately, we cannot guarantee we can provide help for using this site. Data won't be manually curated either.
Purpose: The VESPA program detects signature patterns (atypical amino acid or nucleotide residues) in a set of query sequences relative to a set of background sequences. Please read the VESPA explanation.
