*Hi, I am dealing with Affy exon array data using aroma.affymetrix and had some problems while loading CEL files, see the following code:*
> cdf <- AffymetrixCdfFile$byChipType("HuEx-1_0-st-v2",tags="coreR3,A20071112,EP") > cdf AffymetrixCdfFile: Path: annotationData/chipTypes/HuEx-1_0-st-v2 Filename: HuEx-1_0-st-v2,coreR3,A20071112,EP.cdf File size: 38.25 MB (40108891 bytes) Chip type: HuEx-1_0-st-v2,coreR3,A20071112,EP RAM: 0.00MB File format: v4 (binary; XDA) Dimension: 2560x2560 Number of cells: 6553600 Number of units: 18708 Cells per unit: 350.31 Number of QC units: 1 > cs <- AffymetrixCelSet$byName("try",cdf=cdf) Exception: Failed to setup a data set for any of 1 data directories located.
