Dear All,
 
I have a problem of reading cel files from MOE430A type. The error I get is 

> library(affy)
> res=justRMA()
 
Error in just.rma(filenames = l$filenames, phenoData = l$phenoData, description = l$description,  : 

 Is c:/temp/mouse430a/Green.CEL really a CEL file? tried reading as text, gzipped text, binary, gzipped binary, command console and gzipped command console formats
