I preprocessed the data using RMA and mapped to the gene symbol but found out repeated gene symbol with different expression values. How to get unique gene symbol??? Thanks
Which array is this? You have duplicated gene names because many genes have multiple probes (e.g., for different transcripts).
So what all steps can i do to get the unique genes?? This is for affymetrix platform.
Which affymetrix array?
The GeneChip Human Genome U133 Plus 2.0 Array
I think the affy package has a method for that. It's been a few years though...
