I am using a Custom cdf file  *HTA-2_0,Transcript,binary.cdf* in aroma. 
affymetrix to analyse HTA-2_0 chip .  I am using the following commands to 
set up CDF and CEL files.

>chipType <- "HTA-2_0"
>cdf <- AffymetrixCdfFile$byChipType(chipType, tags="Transcript,binary")

Path: annotationData/chipTypes/HTA-2_0
Filename: HTA-2_0,Transcript,binary.cdf
File size: 7.55 MB (7921066 bytes)
Chip type: HTA-2_0,Transcript,binary
RAM: 0.00MB
File format: v4 (binary; XDA)
Dimension: 2560x2560
Number of cells: 6553600
Number of units: 18490
Cells per unit: 354.44
Number of QC units: 0


However I am unable to read the CEL files as it gives me the following 

Error: Failed to setup a data set for any of 1 data directories located. 
The following reasons were reported: (1) Failed to create AffymetrixCdfFile 
object. Could not locate an annotation data file for chip type 'HTA-2_0' 
(without requiring any tags) and with filename extension 'cdf'. (while 
trying './rawData/Krzy/HTA-2_0').

My directory structure is: 
annotationData< chipTypes<HTA-2_0<HTA-2_0,Transcript,binary.cdf

Please can someone help me understanding what I am doing wrong. I have used 
aroma.affymetrix for exon arrays and I never came across this issue. Is it 
something to do with the CDF file? 

Kind Regards,
