WebMar 4, 2011 · Prune tree to a list of taxa. Using the {ape} function drop.tip () we can easily excise a single taxon or a list of taxa from our "phylo" tree object in R. However, it is not immediately obvious how to prune the tree to include, rather than exclude, a specific list of tips. Trina Roberts (now at NESCent) shared a trick to do this with me some ... WebPick Operational Taxonomic Units (OTUs) based on sequence similarity within the reads, and pick a representative sequence from each OTU. Assign the OTU to a taxonomic identity using reference databases. Align the OTU sequences and create a phylogenetic tree.
