[BioC] Using gcrma with \"Affymetrix GeneChip miRNA v1.0\" data

Dear List,

I am working with some "Affymetrix GeneChip miRNA v1.0" chip data and am recieving an error upon executing the gcrma method. Is this error to do with the NSB estimation by any chance? If so is my only solution to use simply rma instead?

Thanks,

Scott
