Hi,

I am trying to read annotation file of CytoScanHD_Array, but somehow it 
could not locate it.

I followed the tutorial in the 
web http://aroma-project.org/setup/annotationData/. I am using NetAffx 
Annotation Files (I could not find CDF file) .
I created folder annotationData/chipTypes/CytoScanHD_Array/NetAffx/  and 
put annotation file CytoScanHD_Array_annot.csv there.

I ran AffymetrixNetAffxCsvFile$byChipType("CytoScanHD_Array") at parent 
directory of annotationData.

It gave error "Error in grep(pattern, basename(files0)) : invalid 'pattern' 
argument"

Does anyone know what was wrong ?

Br,
C.Y
