Hello, I'm trying to run some quality control (qc) on a bunch of raw files retrieved from ArrayExpress, using simpleaffy, with the code: mixture.batch <- ReadAffy() mixture.qc <- qc(mixture.batch) However, when I get to an experiment which has not used the "hgu133plus2cdf" platform (In this case, it is experiment E-GEOD-33443), I encounter a warning: Error in getCdfInfo(object) : Could not obtain CDF environment, problems encountered: Specified environment does not contain hugene10stv1.r3cdf Library - package hugene10stv1.r3cdf not installed Bioconductor - hugene10stv1.r3cdf not available In addition: Warning message: In qc.affy(unnormalised, ...) : CDF Environment name ' hgu133plus2cdf ' does not match cdfname ' hugene10stv1.r3cdf ' Any help would be appreciated, thank you.
