Uses the old Nexus.Trees parser to extract the trees, converts them back to plain Newick trees, and feeds those strings through the new Newick parser. This way we don't have to modify the Nexus module yet. (Perhaps we'll eventually change Nexus to use the new NewickIO parser directly.) cs:fdd|jD}tj|jj|jj||jj|jjdS)Ncsg|] }|qS)node).0n) node2cladenxtreerE/var/www/html/myenv/lib/python3.10/site-packages/Bio/Phylo/NexusIO.py .sz-parse..node2clade..) branch_lengthnameclades confidencecomment)succrCladedata branchlengthtaxonsupportr)r r subcladesr )r r r -szparse..node2clade)rootrootedrweightN) rtreesrrrTreerrr)handlenexr newrootrrr parse s    r#cKst|}t|}ddt|jd ddd|D}ddtdd|DD}tt|d |d |d }| |t|S)zWrite a new Nexus file containing the given trees.
