SERES + GUIDANCE2 performance using different choices for anchor length. Results are shown for five 10-taxon medium-gap-length model conditions (named 10.A through 10.E in order of generally increasing sequence divergence). We evaluated the performance of SERES + GUIDANCE2 where anchor length in bp was either 3, 5, 10, 30, or 50. We calculated each method’s precision-recall (PR) and receiver operating characteristic (ROC) curves. Performance is evaluated based upon aggregate area under curve (AUC) across all replicates for a model condition (\(n=20\))
