What changed in the DIADEM metric released on 2/19/2010? Why are some of nodes that should be scored as continuations being scored as misses in the prior release?
A. Four errors exist in the Diadem Metric code introduced in the release (11/25/09) that contained new functionality for improving the accuracy of the metric. The first error causes a NullPointerException if either the gold standard or test reconstruction has no bifurcations (note: all of the provided gold standards have at least one bifurcation). The second error causes a NullPointerException if either reconstruction has a bifurcation at their second compartment (i.e. the second point in the SWC file), such as in NC_06.swc. The third error causes only one of the root’s subtrees to be considered if the root is a bifurcation (or multifurcation). None of the gold standard files have bifurcations at the root node, so this would only be an issue for test reconstructions. The fourth error occurs when more than one bifurcation is missed in a row. While checking the descendants and ancestors of the gold standard nodes for matching nodes in the test tree, the error causes only the immediate ch
