[BioC] is it possible to find sample batch # in CEL files?

[Hooiveld, Guido]

Hi,
Some time ago I came across these lines of code, that could be of help:

Never used it myself, though.

HTH,
Guido

Hi,

I've been downloading raw CEL files from the gene expression omnibus, and have been trying to process them -- i'd like to account for batch effect when computing differential expression, but the authors didn't provide the information explicitly in their annotations. Is this information stored/retrievable through the CEL files through Bioconductor?
