Hi I am new to aroma.affymetrix. I am not sure why the command "AffymetrixCelSet$byName" is not working.
cs <- AffymetrixCelSet$byName("test.CEL",chipType = "../../annotationData/chipTypes/GenomeWideSNP_6") Error in method(static, ...) : [2012-06-18 11:34:57] Exception: Failed to create AffymetrixCdfFile object. Could to locate an annotation data file for chip type '../../annotationData/chipTypes/GenomeWideSNP_6' (without requiring any tags) and with filename extension 'cdf'. at #04. method(static, ...) - method() is in environment 'aroma.core' at #03. AffymetrixCdfFile$byChipType(chipType) - AffymetrixCdfFile$byChipType() is local of the calling function at #02. method(static, ...) - method() is in environment 'aroma.affymetrix' at #01. AffymetrixCelSet$byName("test.CEL", chipType = "../../annotationData/chipTypes/GenomeWideSNP_6") - AffymetrixCelSet$byName() is local of the calling function I think my directory structure is wrong. But i could use some pointers on how to get things moving because i've been trying to get this command working for over 4 days now. Also, another issue is I am able to load CDF files with the basic "AffymetrixCdfFile("GenomeWideSNP_6,Full.CDF") ". But if i use the command AffymetrixCdfFile$byChipType("GenomeWideSNP_6",tags="Full"), it gives me an error. Am I doing something really wrong?
