Pontos
Pontos calculates distance matrices from DNA sequence alignments.
Pontos is an easy-to-use, graphical Java program for the calculation of uncorrected distance (or similarity) matrices from DNA sequence alignments in PHYLIP format. It also creates "difference" alignments from regular ones (and vice-versa).
It can handle gaps and ambiguities in different ways.
Gaps can be:
- all used;
- all ignored;
- ignored only at the ends of the sequences, in a pairwise manner;
- ignored only at the ends, but now globally (in effect trimming the whole alignment...
