Hi, I have a problem with new Cytogenetics Array from Affymetrix. I have original Affy .cdf file from web, but I´m not able to create a cdf- package using make.cdf.package. Thanks for any help. Lenka [[alternative HTML version deleted]]

Lenka Dear Lenka you will increase your chances of getting a useful answer by asking a useful question. You might have a look at the posting guide http://www.bioconductor.org/docs/postingGuide.html in order to find out how to do so. One particularly important point is: "If possible, send a simple and reproducible example along with the output of sessionInfo(). If the example produces an error, also provide the error message and the output of traceback()." Wolfgang Huber EMBL http://www.embl.de/research/units/genome_biology/huber

Using the oligo package, you can import the data from the Cytogenetics arrays (it should be able to download/install the required annotation package, but you can download it directly from http://www.bioconductor.org/packages/release/data/annotation/html/pd.c ytogenetics.array.html ). I don't have any workflow specific for the cyto chip yet, but this should suffice for you to import data and use it in combination with other BioC packages that you may find relevant. b On Tue, Apr 27, 2010 at 12:39 PM, Wolfgang Huber <whuber at="" embl.de=""> wrote: > Lenka Radova scripsit 27/04/10 13:28: >> >> Hi, >> I have a problem with new Cytogenetics Array from Affymetrix.

Hi, I have the original cdf file from Affymetrix web page (Cytogenetics_Array.CDF) in my working directory and I tried the following...

Hi, Lenka. You'll want to use the oligo package, as Benilton suggested, to process this chip type. make.cdf.env is for 3' biased gene expression arrays only, really.

Thanks a lot. The oligo package works.
