This repository contains code and files for reproducing the analysis presented in "Neuropathological and transcriptomic characteristics of the aged brain," [LINK/INFO HERE] the platform paper for the Aging, Dementia, and TBI Study.

To reproduce the analysis, do the following:

  1. Download everything from the Aging, Dementia, and TBI Study download page (http://aging.brain-map.org/download/index) and save it in the same folder
  2. Download this github repository files. Unzip "dataFiles.zip" and save to a folder. Save "TbT_normalization.RData" in the same folder
  3. Save the six .r files from this github repository in a different folder
  4. Update the top several lines of "Code01_ReadInDataAndFormat.r" with the appropriate folder names (from above)
  5. Install the following R packages: sva, WGCNA, gridExtra, ggplot2, gplots, baySeq, edgeR, DESeq, NBPSeq, ROC, and mclust
  6. Run the five numbered code files in order

Some useful websites:
