Looking for conflicting phylogenetic claims

Our tree curation tool has a conflict viewer that allows you to compare a tree to the Open Tree Taxonomy or the Open Tree Synthetic tree. We are in the process of generalizing this feature so that biologists can compare any tree to any other tree. These trees will need to be mapped to the Open Tree Taxonomy.
