- User: Evolutionary Biologist
- Interested in the most recent common ancestor (MRCA) of arabidopsis & populus
Actions/Steps:
...
- The user selects "interested" gene families
- The user is shown the available tree (re prototype NBCI tree) w/ additional information on branches
- The tree shows condensed representation of statistics related to a branch
- statistics per branch: gene family copy #, total gene #,
- a suggestion of condensed representation below
- a pop-up also shows details of the duplications present, one only present here, and potential losses
Use Case #4 and it's relation to Use Case #3
...
So the entry point for #4 is really a GO Category.
A "clickable" tree viewer would be required to handle the user interaction that was discussed. Attached information to the branches of the tree would be available and the user could be presented w/ a popup/bubble containing further details about this information. From this interface, a user could select to see a "reconciled" view (which would be the 3-panel view or similar approach).
A second approach, still clickable, could be done w/ a tabbed view that toggled between the species tree (w/ attached info) and the 'details' corresponding to the attachments in the other tab.
Given the scope of the prototype, such a "clickable" tree viewer is not likely. An approach of 'labeling' the tree so the user would indicate/select "branches of interest" in an interface below the tree.
It would be nice if the user could prune the available tree (NCBI taxonomic tree or "BIG" tree) and control the level of detail shown:

Some ideas on how this might be done were discussed. An example of the hierarchic interface from Phytome was shown:
