Dear all, I would like to use the affylmGUI package to analyze some Affymetrix Human Gene ST arrays. But it seems that Bioconductor does not provide the annotation package hugene10stv1cdf yet - which is needed to work with the affylmGUI library. I get the following error message: Error in getCdfInfo(object): Could not obtain CDF environment, problems encountered: Specified environment does not contain GuGene-1_0-st-v1 Library - package hugene10stv1cdf not installed Bioconductor - hugene10stv1cdf not available. How can I proceed to work with the affylmGUI package? Is there a "hugene10stv1cdf" annotation package available, and where do I have to install it, so that I can work with the affylmGUI library? Thanks for any help! Olivia [[alternative HTML version deleted]]

Hi Olivia, Have you tried using the makecdfenf package to just generate the cdf package from the affy source cdf file? http://www.bioconductor.org/packages/devel/bioc/html/makecdfenv.html And the Affy source files are here: http://www.affymetrix.com/support/technical/byproduct.affx?product =hugene-1_0-st-v1 Marc Prazeres da Costa Olivia wrote: > Dear all, > > I would like to use the affylmGUI package to analyze some Affymetrix Human Gene ST arrays.
