If you are using the new scanner, this means that your .cel files are
likely the new binary format. You need to update to the developmental
version of affy. As I recall, you will also have to update to R-1.8.0 or

I am trying to run the mas5 and rma methods of affy
package on some data of affymetrix. It is supposed to
be scanned from a new scanner. However I am getting
this error where it complains about unknown cdf or cdf
not existing in the repository . I am running on an
older version of R ( R1.7) and bioconductor version of
1.2. Please could anybody guide me in getting around
this problem.
