Hello, I would like to suggest a filtering method based on sample name. FilterCTdata contains a lot of filtering methods but didn't see any to filter based on sample names, Actually i use the match function do remove samples from the analysis. e.g tofilter=c("sample1","sample2",...) exprs(qpcrObj)[,-match(tofilter,colnames(exprs(qpcrObj)))] thanks, david

Hello David, Thanks for the feedback on HTqPCR. I've never really thought of filtering out samples during my own analysis, hence no option in filterCtData. The default way is by doing subsetting, such as qPCRset [,c(1:3,5)], or by using sample names as you do in your example. However, I guess a specific filtering option might also be useful in other cases, such as potentially removing samples that have a high proportion of NA values and can therefore be considered failed plates/ samples. I'll put it on the todo list of HTqPCR improvements.
