I'm starting using bioconductor, expecially affy, on a set of *.cel files. Everything works fine, though I get lots of warnings in: 1) ReadAffy: I'm reading 8 CEL files.I get this warning: the condition has length > 1 and only the first element will be used in: (if(dim(intesity(cel)!=dim.intesity)) I guess that is in read.celfiles where it checks for correct dimension of the arrays. I don't think this is a problem, but I'd like to be sure that it's not my fault. 2) Whatever function I apply to the Affybatch file created it returns me more than 50 warnings, all the same. Ex: probeNames(dati)[1:10] I get this warning(s) 1: the condition has length > 1 and only the first element will be used in: ifis.na(ans[[i]])) next ... Why?

Could you detail "Whatever function I apply to the Affybatch file created" ? Regards, Laurent
