DetectiV is implemented as a package for R, a powerful, opensource software package for statistical programming [10] . Many packages for R already exist for the analysis of biological datasets, including microarray data, and the bioconductor project [11] is just one example of a group of such packages. As it is implemented in R, DetectiV easily integrates with many of the packages available for microarray analysis, including limma [12] , marray [11] and affy [13] .
