[BioC] Can\'t read canine CEL file with ReadAffy()

[James W. MacDonald]

Hi Kaj,

You can try two things. First, check to see if this is the first file 
that you are trying to read. If so, there might have been a problem when 
you downloaded, so you might try re-downloading.

Second, if it is not the first file, you might have a non-canine file in 
the bunch. You could try moving it to its own directory, read it in 
alone using ReadAffy() and then see what kind of celfile it is.

Best,

Jim
