I recently discovered Treemmer (Menardo et al., bioRxiv, 2018) for reducing the complexity of large trees down to a few representative taxa. Turned out to be really useful for my analyses!

Here are just a few crude lines of bash and R code to animate the process of Treemming a phylogenetic tree using ggtree & gganimate.

cd example
../treemmer-animate.sh tree.nwk
Rscript ../treemmer-animate.R
