[ESS-bugs] Affymetrix CEL files

[maouche]

Hello all,

I am trying to read 36 CEL files in R using ReadAffy() command.
I moved all my CEL files in a directory and use the following commands :

> setwd () ## I changed the WD to my cel directory
> library(affy)
> Mycels <- ReadAffy()

Error in read.affybatch(filenames = l$filenames, phenoData =
l$phenoData,: Is N1.CEL really a CEL file? tried reading as text, gzipped
text and binary


Has anyone encountered this problem before?  Can you tell me how to deal
with it ?

Thanks for your help,
