Hi Jianyin and Tom,
I was wondering if there's tutorial about how to plot the dendrogram
from ptraj clustering outputs. I see you used
http://www.bioinformatics.nl/tools/plottree.html in the ptraj
clustering paper. But I still can't figure out how to use that web
site and obtain PHYLIP format from ptraj outputs. Could you shed some
light on this topic?
Thanks a lot in advance,
-DX
