colours on phylogeny tree

I wonder how can I color certain edges on a phylogeny tree. I can visualize my tree using phytreeviewer(mytree), but I couldn't figure out how to change color / width of edges.

Thanks,

Dear Rostam,

I'll try to illustrate how to color with a small example. You could try (something like) the following:

yourtree = phytreeread('pf00002.tree')

This will generate a yourtree from one of MATLABs build-in trees. Now you want to handle the graphical elements of your tree:

h = plot(yourtree,'Type','square')

Inspect h in your workspace. This will give you a bit of a feeling how yourtree looks like.

Now you can set certain properties (such as color), for example by using:

set(h.BranchLines,'Color',[1 0 0])

This will set the color of your branch lines to red.

In a similar way, you can select other elements of yourtree and adjust its properties. I do not know what exactly you are trying to color, but I suggest you have a look at the following documentation pages as well:

plotphytree doc

dendrogram doc

Have fun!
