===What's in this package===
R - R code.  Sub-folder GCAT contains the GCAT package
Rails - Rails code
Testing - testing code, data and documents, outside of any regression tests that may be incorporated directly into R packages or Rails applications 

===Getting started===
First you will need to install Ruby and Ruby on Rails. I suggest using RVM to
install them. Documentation for RVM can be found at: http://rvm.io.

You will need: 
Ruby version 1.9.3p194 and Rails 3.2.15
R version between 3.0.2 and 3.2.0.  

The R package is in subfolder R. To install, do the following:
Open a terminal in the R folder
$  sudo R CMD REMOVE GCAT # do this if an older version of GCAT has been installed
$  sudo R CMD INSTALL GCAT

The rails application is in subfolder Rails.  It runs under Rails 3.2.15.  To run it locally using the default Rails WEBrick web server do the following:
Open a terminal in the Rails folder 
$ bundle install
$ rails s
Open http://0.0.0.0:3000 in a web browser
