This repository contains files associated with our manuscript: "Phylogenetic comparative methods are problematic when applied to gene trees with speciation and duplication nodes: correcting for biases in testing the ortholog conjecture". This analysis is based on reanalyses of a published paper by Dunn et al. (doi:10.1073/pnas.1707515115).
The files include:
Manuscript.Rmd This file contains detailed text of our manuscript and the codes to reproduce our results.
Premanuscript_run_TM.R To save time during knitting of the Manuscript.Rmd file, one needs to run this script first. The outputs are generated and saved as Data_TMRR.rda, also available in https://doi.org/10.5281/zenodo.3354285.
functions_Dunn.R The script adopted from Dunn et al. and renamed. The script contains functions, which were used to reproduce the results of Dunn et al. Some of the functions were further used in our study.
funtion_TM_new.R Additional script of functions written for our analysis.
plos.csl CSL style used in our Manuscript.Rmd file.
TM.bib The Bibliography file of our Rmarkdown file.
These analyses build on the analyses of Dunn et al. Specifically, we import the data file manuscript.RData generated by their script manuscript_kernel.R. We assume this file is in the root directory of this repository and that it is renamed manuscript_dunn.RData. This file includes a variety of objects, including the compara gene tree file (ftp://ftp.ensembl.org/pub/release-75/emf/ensembl-compara/homologies/).
To re-execute our manuscript:
Premanuscript_run_TM.R.Manuscript.Rmd.To rerun all our analyses, you can also execute Premanuscript_run_TM.R, which will regenerate the file Data_TMRR.rda.
