* Merlot is back online.
Dongying Wu presentation on Taxonomic Classification Based on Phylogenetic Trees
* How to calculate which clades in different parts of a tree should be considered the same level?
* Developed formula to calculate depth in a tree for different nodes
* What is the cutoff to use for “species”? (or for a 97% cutoff) 16S alignment
*Calculate clusters with Mothur with 97% cutoff
*Then compare to tree-D based clusters
* How to compare two clusters
* counting pairs
* overlapping analysis
* variation of information
* Did this for rRNA trees
* Compare MI for tree D clusters vs. MOTHUR clusters
* Did this for protein trees for all genomes
* Did this for two trees
