Hi Melissa

the .Rnw file that generated Supplement II is contained within the 
tar-ball 'Additional file 3' on 
http://genomebiology.com/2010/11/10/R106/additional This was done with 
DESeq DESeq_1.1.12, and if your aim is to exactly reproduce that 
supplement, please use versions of all packages (and of R) matching the 
sessionInfo() output at the begin of that document.

If your aim is data analysis, then please a more recent version of R, 
Bioconductor and DESeq. In more recent versions of DESeq, the function 
varianceFitDiagnostics has been rendered into an inactive stub, and the 
package vignette shows you newer and better suggestions on how to check 
fit quality.

	Best wishes
