ENCODE-Networks Source Code for Context-Specific TF Co-Association Analyses

Q:
Hello,
I am interested in your paper published in Nature, 06 September 2012, “Architecture of the human regulatory network derived from ENCODE data”. In particular, we are interested in the framework of context-specific TF co-association analysis described in this paper. We would like to apply this method on our in-house datasets. It’s exciting that the code for these analyses is “Available soon” (the file “enets21.coassoc-code.tgz” on http://encodenets.gersteinlab.org/). Do you know whether the code for co-association analysis in this paper is available now? If so, it might save us a lot of time. Thanks for your help!

A:
The main machine learning method used for the analysis is RuleFit3 which is available here
http://statweb.stanford.edu/~jhf/r-rulefit/rulefit3/R_RuleFit3.html

Detailed instructions on preparing the input data and computing the various scores are in the supplement of the paper.

I don’t have a polished code package that is ready for use for the general public. The code that I wrote for analyses in the paper is here https://code.google.com/p/tf-coassociation/source/browse/#svn%2Ftrunk%2Fscripts . But I have to warn you that its not designed to work on general datasets as it has scripts that were designed to run on our local cluster. The core functions are in
https://code.google.com/p/tf-coassociation/source/browse/trunk/scripts/assoc.matrix.utils.R . The code is reasonably commented so hopefully it should help.
