ity across chips, while gene-level NUSE boxplots don't. And RLE boxplots don't show much heterogeneity either at the exon-level or gene-level. Could someone give me an idea about why this is the case, and whether I should define an outlier based on the gene-level or exon- level NUSE/RL

Hi folks, I have a question related to this topic. I want to generate gene-level expression values using the 3' end probes or 5' end probes only. Looks like creating a custom CDF file containing only the probes I want is the only way for that. Is it correct? Thanks

Hi, I followed your human exon array analysis page, but used gcrma for background correction. http://groups.google.com/group/aroma-affymetrix/web/human-exon-array-analysis?hl=en However, I got errors shown below. Also, can I correct for probe sequence effect, in addition to GC content? > bc <-
