tpsTree

Fit and visualize thin-plate splines on trees. Windows. Performs a least-squares orthogonal generalized Procrustes analysis to obtain a reference and then estimates the splines for each group (internal node) on a tree.

Both ultrametric (e.g., WPGMA and UPGMA trees) and additive trees (using squared change parsimony to estimate the shapes of the HTUs) are supported.
The estimated shapes can be visualized with estimated images in the background (see the tpsSuper program). The file expands into a Windows setup program and associated files.
