Neighbor TreeMaker

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: After sequence input, the next page will give additional options. Gaps can be treated as missing or stripped. The user can choose from various distance models and select 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 FindModel to decide what evolutionary model best fits 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.
