Phylogenetics Workflow and Perpetually Updating Tree

Workflow

A Nascent workflow has been added to the the DNA subway as an education tool. This can serve as a model for integrating phylogenetic analysis tools to the DE.

Perpetually updated TOL

Advice will be sought from the iPToL faculty regrading further requirements.

  • The basic strategy is an automated workflow that will synch with GenBank or other data repository, build or iterate on on a chaacter matrix, re-run the tree building and update the Discovery Environment.
