How best to draw very large trees

[theo-allnutt-bioinformatics]

Hi,

I need to use ete3 to draw and annotate a very large tree (~6000 leaves). I am usign a circular style. I need to be able to zoom in and preserve e.g. font resolution. I have tried .svg but it does not render any text for me. .pdf is better, but when I try to make a large image, it becomes very very faint.

How do users best do this?

Thanks,

T.

e.g. my render line:

t= get_tree(tree1,data,font_size,all_colours) #function to annotate and generate tree

ts = TreeStyle()
ts.show_leaf_name = False
ts.mode='c'

t.render(name1+".pdf", w=8000, dpi=1200,tree_style=ts)

That's challenging for ETE v3. We are working on a new version (ete4 branch on github) that should enable exploring very large trees in both rectangular and circular mode. There is a demo at http://treeview.etetoolkit.org
