Hi there,

I'm trying to read some CEL files from Cytoscan HD arrays with the R package affy but I get this (annoying) error:

> u <- read.affybatch(filenames = list.files(pattern=".CEL$"))
> u
    Error in getCdfInfo(object) :
      Could not obtain CDF environment, problems encountered:
    Specified environment does not contain CytoScanHD_Array
    Library - package cytoscanhdarraycdf not installed
    Bioconductor - cytoscanhdarraycdf not available
    Además: Warning message:
    missing cdf environment! in show(AffyBatch)

I've tried to build this CDF file through aroma package (from Affymetrix) and another error appears:

> cdf <- AffymetrixCdfFile$byChipType("2MO_(CytoScanHD_Array).CEL")
[2019-03-06 17:21:59] Exception: Failed to create AffymetrixCdfFile object. Could not locate an annotation data file for chip type '2MO_(CytoScanHD_Array).CEL' (without requiring any tags) and with filename extension 'cdf'.

Error: Failed to create AffymetrixCdfFile object. Could not locate an annotation data file for chip type '2MO_(CytoScanHD_Array).CEL' (without requiring any tags) and with filename extension 'cdf'.

Anyone could me where can I get this CDF file? Or any way to build it, please? Or to understand the error??

Thanks in advance. Regards.
