Just upload candidate phylogenetic trees in the Newick format, one tree per line as below!
(Line feeds not just after semicolons will be skipped.)

(((a,b),c),(d,(e,f)));
(((a,c),d),(b,(e,f)));
((a,d),(b,e),(c,f));

[To know how to prepare such a group of trees, visit this page.]

You can paste trees to the following box: (Paste sample)
Options:
Threshold support in building consensus tree (Default 75):
Use color representation (ignored if distances are shown):
Use rooted trees:
Output only topologies:
Produce a star-like wheel tree:
Spreading coefficient in 2D tree layout (Default 1.5):
(Refer to the Reference for the options below)
Show strict supports:
Show average distances:

Or, you can upload a file containing trees via the following form:

Notes:
1. The trees must contain the same taxa set at their external nodes.
2. A weight value for each tree can be provided as a real number at the beginning of each line, separated by a white space.

Sample input files:
fig4-5.txt (Real and large data set: 246 fungi phylogenetic trees downloaded from FUNYBASE)
fig1.txt / fig2.txt / fig6.txt / fig6withLengths.txt (artifitial small data sets)
(The file names correpond to the figure numbers in our Publication)

If you are a developer, we would be very grateful if you consider using our Web API.
