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: This tool takes a nucleotide sequence alignment, converts it to NEXUS format, and uses PAUP to generate a tree, which is displayed using the PHYLIP programs Drawgram or Drawtree.
Details: Gaps can be treated as missing or stripped. The user can choose from various distance models and set the number of the outgroup sequence. A version of the input alignment in which the sequences have been reordered to match the order in the tree may be downloaded. Trees are calculated using the neighbor-joining method. You can use our FindModel tool to decide which of the offered models best fit your data.
Disclaimer: This interface only offers very basic, 'quick-and-dirty' phylogenetic analysis. More in-depth analysis is usually needed. For more information see the Tree Tutorial.
