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?

Hi, Scott. See below.

These are contained in a "probe" package and there is no such package available. I have not kept up with how to make such a probe package from scratch, so I won't comment directly. Hopefully, someone else will chime in here. Yes, rma should not need the probe package, so that should probably work for you.
