This is a follow-up to my post over here
I'm collecting the gene expression data from microarray studies. How do we filter the studies performed using a specific platform, e.g. Affymetrix Human Genome U133 Plus 2.0 Array?
Update: How do we filter the data from GSE files? I found a tutorial that shows how to parse from GSE files. But what I could get is the probe ids and the expression values for each sample. For instance, from GDS one could use Table(gds)/Column(gds) to filter the gene synmbols and the sample description. For GSE, it is mentioned that object class is not available. Could someone help me in filtering the gene symbols and sample description from the expression set that is created using GSE data?
