<p><strong>Calculation of trees from alignments</strong></p>\r
<p>Trees are calculated on either the complete alignment, or just the\r
-currently selected group of sequences. There are four different\r
-calculations, using one of two distance measures and constructing the\r
-tree from one of two algorithms :\r
