I would like to use MATLAB to analyze the gene expression data generated by "Affymetrix Human Gene 1.1-ST Array". Affymatrix provided me a CDF file, and they mentioned that they are not supporting this file. However, they are supporting this clf file (HuGene-1_1-st-v1.r4.clf) instead. Please let me know how I could fix this problem.

When I ran the affygcrma function I got this error:

Warning: The ChipType (HuGene-1_1-st-v1) of CEL file
ASFREYT_HuGene1.1ST_C04_2.CEL does not match the ChipType
(HuGene-1_1-st-v1_ascii) of library file HuGene-1_1-st-v1_ascii.CDF.
