Trees using the CRISPR spacer data from data set 1. (A,C,E) NJ
: Neighbor joining tree of times from the unordered model. (B,D,F) RNJ
: Rooted neighbor joining tree of times from the fragment loss model.(A,B) Yp1, (C,D) Yp2, (E,F) Yp3. Branch lengths correspond to the number of events under the specific model. For clarity, the unrooted neighbor joining trees are shown with the root at the same branch as the rooted neighbor joining tree.
