Hello BioC team
I have downloaded an old microarray expression data set for analysis from
NCBI's GEO database.
When I try to normalize the data in R2.9 (OS X Leopard) using justRMA() the
normalization fails as it is looking for a library file called
"ecoliantisensecdf"
and cannot find it.
However if try to download the corresponding library file from Affy''s
website I only get a library file called "Ecoli_ASv2" and not
"ecoliantisense".
Affymetrix insists that this library file works fine with the cel files I
have inside their software (Expression console) and that the array layouts
of the older ecoliantisense and the newer Ecoli_ASv2 are the same. But I
have had no luck trying to use the new library in R.
Is there a possible way to resolve this issue?
Thank you inn advance.
