[BioC] regenerate CEL file from analyzed data

[Benilton Carvalho]

Really depends on the definition of "processed data". If by that you
mean that the user only has the results after something like RMA,
there's nothing you can do to generate a CEL file from that.

If the user has the intensity values prior to preprocessing (ie.,
probe-level data), then one suggestion is to use the affxparser
package (createCel/updateCel).

We have a user here who needs to deposit their data in GEO for publication, but they have lost their original CEL file as the experiments were done 8 years ago. So, I was wondering if any of the Bioconductor modules (or any tool at all) might have the functionality to take a list of probe sets and intensity values and create a CEL file. I realize this is a long shot, but I thought I would throw it out there.
