Hello all, We have a group of array CEL files - half of which are HGU133A and the other half HGU133 Plus 2.0. Unfortunately, I need to compare the similar probe sets across the 2 types of chips. I can read the CEL files into different AffyBatches, but as they are of different sizes, I am unable to perform merge.Affybatch. Is there any workaround to compare the similar probe sets? Your advice would be very, very much appreciated! Min-Han Tan This email message, including any attachments, is for the so...{{dropped}}
