Identifying outlier sequences

[ArtPoon]

What criteria were used to define excessively long terminal branches to identify outlier sequences? Please quantify this statement.

[ArtPoon]

We'll need to go back into the data collection issues and find examples of outliers being excluded, record their terminal branch length (or shared branch length if multiple, closely related outliers) and how they relate to the overall distribution of terminal branch lengths.

To go over the original workflow:

• we downloaded a list of accession numbers
• used accession list to retrieve CDS sequences
• mapped CDSs to reference genes
• codon alignment (step 2)
• step 3 filtering involved building a tree
