[BioC] justRMA => logarithmic data ?

[Heike Pospisil]

Dear list members,

I have an additional question concerning my affymetrix analysis.

I performed justRMA on 79 CEL-files.

data<-justRMA()

The resulting expression data range from ~3 to ~14.

min(exprs(data))
max(exprs(data))

Now, only for clarifying, are these values already logarithmised? I have read 
about the thresholds for the golub data that are much larger (100 and 16,000), 
but log2(16000)is ~14 - and so I think, that I have already logarithmic data. Am 
I right?

Thanks a lot for your help.

Best wishes,
Heike
