Dear Reema, I'd like to ask you, have you got any help with this issue? I've the same problem. Dear All, Has anybody knows what's wrong here?

Dear all This message will occur if all the probes have the same value across all samples, I.e. The gene has zero sample variance. You will need to remove these probes from the analysis.

Thank You All for fast reply. I've checked row variance and indeed some values must be close to 0. > xv=rowVars(exprs(AFY2me)) > summary(xv) Min. 1st Qu. Median Mean 3rd Qu. Max 0.001699 0.044130 0.105300 0.310600 0.258800 20.960000 Actually this low variance looks strange for me - it is data from experiment with two treatments fungal inoculation and mock inoculation. So I'm suprised - I should check everything once more. I'll also check the code provided by Reema - thank you! --- Maciej Jonczyk, Department of Plant Molecular Ecophysiology Institute of Plant Experimental Biology Faculty of Biology, University of Warsaw 02-096 Warszawa, Miecznikowa 1 On Mon, 26 Sep 2011 07:18:50 +0800, Hyung Won Choi wrote: > Are there any genes for which variance is zero? > > Hyungwon > > Sent from my Windows Phone > ------------------------- > From: Debashis Ghosh > Sent: Monday, 26 September, 2011 5:51 AM > To: mjonczyk > Cc: reema28sep at gmail.com; bioconductor at r-project.org; Hyung Won Choi > Subject: Re: [BioC] missing value where TRUE/FALSE needed (metaArray) > > Dear all > > This message will occur if all the probes have the same value across > all > samples, I.e.

Dear Hyungwon, dear All, Data is on log scale. I've checked other two studies which I'm going to merge to metaanalysis and variances' ranges are similar. study 2 Min. 1st Qu. Median Mean 3rd Qu. Max. 0.002281 0.106800 0.309800 0.783000 0.896700 19.610000 study 3 Min. 1st Qu. Median Mean 3rd Qu. Max. 0.000472 0.047810 0.120300 0.344400 0.307800 20.290000 So what is minimal variance which don't cause the error?
