Hi all, I am trying to parse out paup output such as this one: tree PAUP_1 = [&U] (1:4,2:20,((3:14,5:200):17,4:13):24); What I want is to extract the length for each one. The number after : is the length For this case: Length of 1 will be 4 Length of 2 will be 20 Length of 3 will be 14+17+24=55 Length of 5 will be 200+17+24=241 Length of 4 will be 13+24=3 Naturally, the output gets pretty large and complicated and before I fire up my editor and start coding: are there any tools/scripts outhere that extract this information already and are available for download? Thanks, Ognen
