Hi BioC guys,
I'm having trouble opening some CEL files from an old project on the
RG_U34A chip. When I try to use ReadAffy, I get this error:
Error in read.affybatch(filenames = l$filenames, phenoData = l$phenoData, :
Is ***01_N1.CEL really a CEL file? tried reading as text,
gzipped text and binary
Also, the file does not open as a text file (so it's probably binary).
I tried using Affy's Cell File Conversion Tool to convert from
'Version 4' to 'Version 3', but it can't open the files (and they're
not read-only, which is a common mistake with that tool).
Any help you can offer would be appreciated. Thanks very much,
