Hi, I am new to the probe match package altcdfenvs, when I was trying the code from the link: http://127.0.0.1:21417/library/altcdfenvs/html/matchAffyProbes.html library(hgu133aprobe) filename <- system.file("exampleData", "sample.fasta", package="altcdfenvs") fasta.seq <- readFASTA(filename) targets <- unlist(lapply(fasta.seq, "[[", "seq")) names(targets) <- lapply(fasta.seq, "[[", "desc") names(targets) <- sub("^>.+\\|(NM[^ \\|]+|Hs[^ \\|]+)\\| ? .+$", "", names(targets)) m <- matchAffyProbes(hgu133aprobe, targets, "HG-U133A") The error msg is Error in validObject(.Object) : invalid class "AffyProbesMatch" object: labels should be unique. Any idea what's the problem? Thanks, -Jack [[alternative HTML version deleted]]

A guess: You have sum(duplicated(names(targets))) > 0 And this is obviously not something you want.
