Hi, there, I tried this fdrawgram several times recently. I must say that is a "slow" tool. For a 45 species tree, it took more than 10 minutes to generate the png file. I found a better tool online at http://cgi-www.daimi.au.dk/cgi-chili/ phyfi/go . The cons are: 1. first, 2. colorful, 3. multi-format (jpg, png, etc) for download. So if we replace the old PHYLIP drawing program with this new one, that will be much better. Best, Ying
