Probability of Synapomorphy was designed as an R script that implements a new method for evaluating synapomorphy on phylogenetic trees.
All you have to do is install R and run the script. A method that quantifies the pattern of character state distribution over a cladogram and as such is free...

This simple m-file plots the Soft Handover probability as a function of the Soft Handover Threshold value used in the UTRA Soft Handover Algorithm. The relationship has been dertived by taking the ratio between the Cell area where Soft Handovers are enabled and the total Cell area.
