[BioC] R 2.15.1 ReadAffy error

[DaveW [guest]]

I'm attempting to read Affymetrix CEL files and failing miserably. Any thoughts.

Error in read.celfile.header(as.character(filenames[[1]])) : 
  Is /home/dw/HDgenotypes/CEL files/Titan_0020_772G_Hannotte_772_001_D06.CEL really a CEL file? tried reading as text, gzipped text, binary, gzipped binary, command console and gzipped command console formats

Here is the output of the first few lines of one of the CEL files in case this helps anyone to spot the issue:
