Hi, I am trying to load data from .cel files from custom affy chips, but I get the errors below. The first error was because I needed to load the cdf environment. So, I attempted to make the cdf environment and got the second error. The cdf file is from resequencing data. Is it possible to convert a resequencing CDF file to a genotyping CDF file? Or, is there another function I can use to load a resequencing CDF file? Thanks, Charlyn > raw.data <- ReadAffy() > raw.data Error in getCdfInfo(object) : Could not obtain CDF environment, problems encountered: Specified environment does not contain DPGP3_XX_01 Library - package dpgp3xx01cdf not installed Data for package affy did not contain dpgp3xx01cdf Bioconductor - dpgp3xx01cdf not available AffyBatch object size of arrays=1600x1552 features (19406 kb) cdf=DPGP3_XX_01 (??? affyids) number of samples=1 Error in getCdfInfo(object) : Could not obtain CDF environment, problems encountered: Specified environment does not contain DPGP3_XX_01 Library - package dpgp3xx01cdf not installed Data for package affy did not contain dpgp3xx01cdf Bioconductor - dpgp3xx01cdf not available In addition: Warning message: missing cdf environment ! in: show(<s4 object="" of="" class="" "affybatch"="">) > make.cdf.env("DPGP3_XX_01.cdf") Error in make.cdf.env("DPGP3_XX_01.cdf") : makecdfenv does not currently know how to handle cdf files of this type (ie not expression or genotyping)
