Hi Tarun, I'm not quite sure what you are looking for. Do you mean the "expression levels" alias "normalised intensisities"? If that is so then you can access these values with > exprs(yourExprSetObject) It returns an array of the dimensions numberofgenes x numberofarrays. Note that these values are normalised AND summarised. If you wish unsummarised values, just normalised, then you have to set summary.method=NULL when you call expresso. Hope that helps, Benjamin Am Dienstag, den 23.05.2006, 15:01 -0700 schrieb Tarun Nayar: > Hi, > > How can I output normalized data from an exprSet for all probe sets and > all arrays in an experiment? > > ...the results.summary and write.annotation functions appear to only > work once a pairwise.comparison is performed (?) > > thanks > > Tarun Nayar > Genome Sciences Centre > Vancouver, BC > > [[alternative HTML version deleted]] > > _______________________________________________ > Bioconductor mailing list > Bioconductor at stat.math.ethz.ch > https://stat.ethz.ch/mailman/listinfo/bioconductor > Search the archives: http://news.gmane.org/gmane.science.biology.informatics.conductor > -- Benjamin Otto Universitaetsklinikum Eppendorf Hamburg Institut fuer Klinische Chemie Martinistrasse 52 20246 Hamburg

Hi Tarun, If you just want to export the values from an exprSet, check out exprs2excel(). Jenny At 03:55 AM 5/24/2006, botto wrote: >Hi Tarun, > >I'm not quite sure what you are looking for.
