Free Tree

Freeware program for construction and bootstrap (and jackknife) analysis of phylogenetic trees from binary data (RAPD, RFLP, AFLP etc.)

Recent windows version  Download here (archive containing 3 files: program, sample data, short manual)


Easy setup (none, just autoextrac and run)

Easy operation (paste your data from spredsheet and press run)

Performs phenetic (UPGMA) and fylogenetic (NJ) analyses

Most universal resampling techniques (bootstrapping, jackknifing, OUT-jackknifing)

All in one (for better presentation of data you will probably need some tree-drawing program, for example Treeview available here)
