I'm doing some analysis on GSE7829. The data supplied in the GSE Matrix has been processed by Z-normalization (instead of the more common RMA). The raw intensity values are also available in the GSE SOFT "RAW" column and I would like to RMA-normalize these raw values. How do I approach this (the CEL files are not supplied)?
I have extracted the "RAW" column from the GSE SOFT file and built an ExpressionSet object. I'm stuck here as the RMA functions take either CEL or AffyBatch objects as input. Any suggestions?
