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
