Answer: A: liandwong and mas5
... I've tried with larger probe pairs (207149 of ath1121501 array) but have the same problem. However, there are some probe sets with only 4 pairs. Could it be because of this small number of pairs per set? When I use traceback(); > traceback() 12: stop("need at least four unique `x' values") 11: s ...

Answer: A: altcdfenvs
... Thanks Laurent for the tip but I encountered other problems if I create enough identifiers. When I created one unique identifier for each probe pair I want to be inside the new cdf, then I would get 99112 probe *sets* because > length(unique(ind)) [1] 99112 This isn't exactly what I have in mind ...

altcdfenvs
... Dear All I was trying to use a trial data (Dilution) to create a new cdf using "altcdfenvs". Instead of using "matchprobes", I created the "m": ind <- c(seq(1,199084,by=11), seq(1,199084,by=10), seq(1,199084,by=9), seq(1,199084,by=8), seq(1,199084,by=7), seq(1,199084,by=6)) m.dil <- new.en ...

Affy empty line
... Dear List, I'm running R (version 1.9.0) and affy (1.3.x). When I read one of my ATH1-121501.CEL files, I encountered this message: arab <- ReadAffy("ATHfile.CEL") Warning: found an empty line where not expected in ATHfile.CEL. This means that there is a cel intensity missing from the cel file ...

Selecting probe pairs for analysis
... Hi All, I'm interested in calculating the expression measure using only 8 pairs of probes from each probe set of Arabidopsis genechip (i.e instead of using the whole 11 pairs of a probe set). After searching through the archive, I found that I can create a new cdf environment that excludes the pair ...
