Hello,

I have a big newick tree (7000+ nodes) I want to pinpoint a specific list of nodes (change color, highlight or change font size ... ) is there any tool that allows me to do it by command line or python code ? if yes I need the title of the option in the tool that allows to do this
I think the [ETE toolkit][1] is exactly what you describe

Tree visualization is fully programmatic, check [this part of the tutorial][2].
