Hi all, I have problem with the miRNA microarray from Affymetrix. I got the following error message: data<-ReadAffy() Error in getCdfInfo(object) :   Could not obtain CDF environment, problems encountered:    Specified environment does not contain miRNA-1_0_2Xgain    Library - package mirna102xgaincdf not installed    Bioconductor - mirna102xgaincdf not available Where can I find the win binary packages? Thanks. Cunye [[alternative HTML version deleted]]

Because the CDF package does not involve binary code, there is no need for a windows binary. install.packages or biocLite should install it properly. Furthermore it appears to be available on the release branch.

Hi Cunye, An CDF environment for this array is available at the developers branch. Ideally you will use the dev version of R/BioC with this CDF as well. http://www.bioconductor.org/help/bioc- views/devel/data/annotation/html/mirna102xgaincdf.html You may also want to see: http://article.gmane.org/gmane.science.biology.informatics.conductor/3 3123 HTH, Guido ------------------------------------------------ Guido Hooiveld, PhD Nutrition, Metabolism & Genomics Group Division of Human Nutrition Wageningen University Biotechnion, Bomenweg 2 NL-6703 HD Wageningen the Netherlands tel: (+)31 317 485788 fax: (+)31 317 483342 email:????? guido.hooiveld at wur.nl internet:?? http://nutrigene.4t.com http://www.researcherid.com/rid/F-4912-2010 -----Original Message----- From: bioconductor-bounces@r-project.org [mailto:bioconductor- bounces@r-project.org] On Behalf Of cunye qiao Sent: Monday, February 21, 2011 21:24 To: bioconductor at r-project.org Subject: [BioC] miRNA-1_0_2Xgain win binary packages Hi all, ?
