[BioC] .CEL file

[James W. MacDonald]

BRB array tools uses R and bioconductor tools to process the celfiles. 
The only thing it does in Excel is to make comparisons after the arrays 
have been processed.

And as I said before, I can't help you with this. There are any number 
of ways to process raw Affymetrix data that are fast, free and already 
in existence. This is a solved problem, so if you want to solve it 
again using Excel, then have at it. But I wouldn't expect that many 
people want to spend much time helping you.

Best,

Jim
