Hi,

I'm trying to extract a matrix of intensity values from an AffyBatch object.

I know I can have them using
> Intensity(AffyBatch)
or
>exprs(AffyBatch)

but I would like to have a full matrix with the probe names.
Unfortunately I can't find a way of doing it.

There are several way of extracting the names of the probes, but not in the
same order or magnitude compared to the intensity array.

> length(geneNames(rawData))[1] 18952> length(probeNames(rawData))[1] 265358> dim(intensity(rawData))[1] 535824     12> dim(exprs(rawData))[1] 535824     12

Does anyone has an idea of how to extract these Values into a matrix. I have
the original CEL files.

Even a way outside of R will be welcome.

Thanks

Assa
