Thanks for reading. I am doing some work with Affymetrix SNP 6.0 arrays using NExus for OncoScan software. I would like to export the data in order to do some hierarchical clustering, heatmaps, correlation matrices, etc, but the only format I can get is a BED format (.BGR) , and it does not provide with the names of the samples, just coordinates, gains and loses. Does anybody have a better idea? Anything will be more than welcomed, thanks for your time.
