- <p><strong>Tree Construction Methods</strong></p>
-<p>Jalview currently supports two kinds of agglomerative clustering
-methods. These are not intended to substitute for rigorous
-phylogenetic tree construction, and may fail on very large alignments.
-<ul>
-<li><strong>UPGMA tree</strong><br>
- UPGMA stands for Unweighted Pair-Group Method using Arithmetic
- averages. Clusters are iteratively formed and extended by finding a
- non-member sequence with the lowest average dissimilarity over the
- cluster members.
-<p></p>
-</li>
-<li><strong>Neighbour Joining tree</strong><br>
- First described in 1987 by Saitou and Nei, this method applies a
- greedy algorithm to find the tree with the shortest branch
- lengths.<br>
- This method, as implemented in Jalview, is considerably more
- expensive than UPGMA.
-</li>
-</ul>
-<p>A newly calculated tree will be displayed in a new <a
-href="../calculations/treeviewer.html">tree viewing window</a>. In
-addition, a new entry with the same tree viewer window name will be added in the Sort
-menu so that the alignment can be reordered to reflect the ordering of
-the leafs of the tree. If the tree was calculated on a selected region
-of the alignment, then the title of the tree view will reflect this.</p>
