Hi

As I understand from your question, you want to analyse binary data and construct a dendrogram. There are a lot of free programs for it but I can suggest:

1. Phylip, it contains different programs for different analyses.

2. PAUP, PAUP 5.0 is testing and free now.

3. PAST 4, it is for paleontological and ecological studies, but it has a lot of functions.

4. DarWin 6.0, it is using dissimilarities, you can easily make phylogenies with it.

Best wishes,

Hi, for small-scale projects, PyElph, GelJ, and ImageJ and for something bigger options be like BioNumerics GelCompar II (trials)

Thanks a lot Mam
