Dear Michael Love and list members, I'm used to analyze RNA-seq data with your nice DESeq2 package (1.2.0) and I sometimes have to test complex null hypotheses using contrasts. For one of my project, I would like using multiple contrasts, i.e. testing for example (H0: beta1-beta2 = beta3-beta4 = 0) against (H1: beta1-beta2 != 0 and/or beta3-beta4 != 0), where the beta's are the regression coefficients of the models. To do so, I would like using a numeric matrix for the contrast argument in results(), but it only accepts a numeric vector. Hence, I was wondering if you planned to extend DESeq2 to the use of multiple contrasts? Best regards, Hugo -- Hugo Varet Plate-Forme Transcriptome et Epig?nome Institut Pasteur

hi Hugo, We are not planning at the moment to have results() generate multiple contrasts, but I will keep it in mind. best, Mike On Mon, Dec 23, 2013 at 5:10 AM, Hugo Varet <hugo.varet@pasteur.fr> wrote: > Dear Michael Love and list members, > > I'm used to analyze RNA-seq data with your nice DESeq2 package (1.2.0) and > I sometimes have to test complex null hypotheses using contrasts.
