Background

This repository includes the source code for the analyses I presented at the EDEN sponsored symposium "Understanding First Order Phenotypes: Transcriptomics for Emerging Model Systems" at the 2013 SICB conference, described in abstract S4-2.1.

This study is a collaborative project by Brown University faculty members:

All collaborators contributed to the code presented here.

Additional details will be provided in a forthcoming publication. A preprint of this publication is available at:

Dunn, CW, X Luo, and Z Wu (2013) Phylogenetic analysis of gene expression. arXiv:1302.2978

Many thanks to Joe Felsenstein for helpful discussions about multivariate comparative analyses.

Use

To run the simulation and analyses, execute the following shell command:

R CMD BATCH simulation.r

This will regenerate the pdf file.
