Hi, All, I am using simpleaffy package to analyze affydata. Affy chip type is drosophila2. I got following error message: > qc<-qc(raw25, x.mas5) Error in qc.affy(unnormalised, ...) : I'm sorry, I do not know about chip type: drosophila2cdf I already installed dropsophila2 CDF on my computer. Since in simpleaffy website, the tested chip type doesn't include drosophila2. Does it mean simpleaffy could not analyze drosophila2 data yet? Thanks in advance. Yihuan
