| Setup | Download files required for the lesson | |
| 00:00 | 1. Package version |
How do you know your installed package versions?
How do you instal a certain version of a package? |
| 00:10 | 2. Finding your taxa in the Open Tree of Life Taxonomy |
What is the Open Tree of Life Taxonomy?
What are OTT ids? What does TNRS stand for? |
| 00:20 | 3. Getting a piece of the Synthetic Open Tree of Life |
What is the synthetic Open Tree of Life?
How do I interact with it? Why is my taxon not in the tree? |
| 00:30 | 4. Dealing with "broken" and "invalid" taxa |
What is a broken taxon?
How do I detect it? |
| 00:40 | 5. Getting an induced subtree of all taxa within a taxonomic rank | How do I get all taxa from a certain taxonomic rank? |
| 00:50 | 6. Getting studies and trees supporting relationships in a synthetic subtree | What are the original studies supporting relationships in my synthetic subtree? |
| 01:00 | 7. Getting branch length information (proportional to time) for you taxa |
How do I find supporting trees that include branch lengths?
How do I subset them to include just the taxa I am interested in? |
| 01:10 | 8. Summarizing branch length information |
How do I summarize information from different source chronograms?
How do I choose a preferred source chronogram? |
| 01:20 | Finish |
The actual schedule may vary slightly depending on the topics and exercises chosen by the instructor.
