Hello everyone, I have a question regarding normalization for a library size in DESeq. I have a set of samples, which I had normalized with a function estimateSizeFactors. Is there an option to normalized an additional sample with respect to normalized previously set of samples. I know that in the normalization in EdgeR treats a first sample as a reference by default. How can I do it in DESeq? regards Dorota -- ================================================================== Dorota Herman, PhD VIB Department of Plant Systems Biology, Ghent University Technologiepark 927 9052 Gent, Belgium Tel: +32 (0)9 3313692 Email:dorota.herman at psb.vib-ugent.be Web: http://www.psb.ugent.be

hi Dorota, I don't know if you are using DESeq or DESeq2, but in the latter I have added an argument geoMeans to estimateSizeFactors which allows you to provide the geometric means from a previous dataset to normalize a new one. See the Examples section for ?estimateSizeFactors for DESeq2 v1.2 Mike On Thu, Nov 21, 2013 at 6:24 AM, Dorota Herman < dorota.herman@psb.vib-ugent.be> wrote: > Hello everyone, > > I have a question regarding normalization for a library size in DESeq.
