The data associated with the article "Extracting Phylogenetic Signal from Phylogenomic Data: 
Higher-Level Relationships of the Nightbirds (Strisores)" published in 2019 in Molecular 
Phylogenetics and Evolution by Noor D. White and Michael J. Braun includes the following files:

Matrices_phylip.tar.gz: Concatenated nucleotide matrices used in this study, including character sets detailing individual UCE loci

Tree files are those found in Figure 5 of the manuscript. They include:
