+**Song et al**:  
+We include here sample input files based on the [Song et al.](http://www.pnas.org/content/109/37/14942.short) dataset of 37 mammalian species and 442 genes. 
+We have removed 23 problematic genes (21 mislabeled genes and 2 genes we classified as outliers) and 
+we have also re-estimated gene trees using RAxML on the alignments that authors of that paper kindly provided to us. 
+We have also included 200 replicates of bootstrapped gene trees for the gene trees we estimated on the Song et al. dataset. 
+
+**Simulation**:
+We have included simulations based on the Song et al. dataset with increases rates of ILS. 
+
+**primates:**
+We have also created a reduced version of the Song et al. dataset with 9 primates, tree shrews, and 4 other mammalian taxa. This dataset is provided for testing the exact version. 
+
+**14 taxon simulation:**
+Simulated used SimPhy with extreme levels of ILS
+
+**100-taxon simulations:**
+A simulated dataset with 100 taxa and 2500 bootstrap replicate gene trees is also provided for testing large datasets.
