description: Data from "A comparison of methods for quantifying treelikeness"Figshare repository Caitlin Cherryh, 2024OverviewThis Figshare repository contains results from the manuscript "A comparison of methods for quantifying treelikeness". The GitHub repository for this project (https://github.com/caitlinch/treelikeness-metrics/) contains instructions and all scripts necessary to repeat these analyses.Empirical dataWe applied treelikeness metrics to two empirical datasets:<b>Original dataset: </b>Metazoa_Choano_RCFV_strict.phyWhelan N.V., Kocot K.M., Moroz T.P., Mukherjee K., Williams P., Paulay G., Moroz L.L., Halanych K.M., 2017.

(2023) studycollated_gene_output.zipIntermediate results from applying the parametric bootstrap to empirical datasets.A parametric bootstrap was applied to each gene in the Whelan et al. (2017) and McCarthy et al. (2023) alignments to determine whether the null hypothesis of treelikeness could be rejected. To perform the parametric bootstrap, for each gene we generated 99 simulated genes with the same underlying tree and pattern of evolution, then calculated treelikeness metrics for the original gene and all 99 replicates. This directory contains a .csv file for each gene, with a single row containing the treelikeness metric results for the gene and 99 rows containing the treelikeness metric results for each simulated alignment.gene_treelikeness_pvalues.csvFinal parametric bootstrap results (including p-value to assess the null hypothesis of treelikeness) and treelikeness metric results for each gene in both empirical datasets.
