It could be the "Random" ones. Unless there is a good reason, why you want to keep these control probes that do not match the genome in your data for further analyses, I would suggest to drop them before preprocessing. loess_test <- preprocess(test[test$genes$Status=="Probe",], method="loess",returnMAList=TRUE) If you want to keep the Random probes, maybe you should discard only those that have missing values already in the RGList. Hope this helps.

sorry, I forgot to CC to the list .. ---------- Forwarded Message ---------- Subject: Re: [BioC] Ringo: Error in preprocess() with R-2.7.0, but not with R-2.5.0 Date: Friday 04 July 2008 11:00 From: Ulrike Goebel <ugoebel@mpiz-koeln.mpg.de> To: Joern Toedling <toedling at="" ebi.ac.uk=""> Hi Joern, thanks for your suggestion .. but this didn't help: I'm still getting the same error. Trying to trace it back, I found that it is generated in backgroundCorrect debug: res <- .Internal(optim(par, fn1, gr1, method, con, lower, upper)) Stack trace: where 1: optim(par = c(mu, log(sigma), log(alpha)), fn = normexp.m2loglik.saddle, control = list(trace = as.integer(trace)), x = x) where 2: switch(method, saddle = optim(par = c(mu, log(sigma), log(alpha)), fn = normexp.m2loglik.saddle, control = list(trace = as.integer(trace)), x = x), neldermean = optim(par = c(mu, log(sigma), log(alpha)), fn = normexp.m2loglik, control = list(trace = as.integer(trace)), x = x), bfgs = optim(par = c(mu, log(sigma), log(alpha)), fn = normexp.m2loglik, gr = normexp.grad, method = c("BFGS"), control = list(trace = as.integer(trace)), x = x)) where 3: normexp.fit(x, method = method) where 4: backgroundCorrect(RG$G - RG$Gb, method = method, verbose = verbose) where 5: switch(method, subtract = { [lines omitted] where 6: backgroundCorrect(myRG, method = "normexp", offset = 50) where 7: preprocess(test2[test2$genes$Status == "Probe", ], method = "loess", returnMAList = TRUE, bc.method = "none") I realize that preprocess is using backgroundCorrect(myRG, method = "normexp", offset = 50), without a way to change the correction method. Actually, in my datasets (and generally in NimbleGen data ?), the MM probes are not used, and the corresponding column is all-zero. So why at all would one want to apply a background correction method ? What I still don't understand is that the problem is happening only with this one array (I can't see anything special with it) ... Greetings & thanks for the quick answer !

Hello Ulrike, I agree that background correction does not make much sense here. "MM" probes, however, are an Affymetrix thing and I guess you mean that the red and green background estimates in the list elements Rb and Gb are all zero. I am going to remove the calling of "backgroundCorrect" within "preprocess" (currently happens for methods "loess" and "median" only) and leave it to the user if they want to call it separately on their RGList before calling "preprocess". In general, I did not find "loess" normalization very useful for two-color ChIP-chip data, since ChIP and input sample are usually very different from each other. So for the moment, I suggest you use another preprocessing method or, if you still want to use "loess", edit the function and remove the backgroundCorrect, or wait a few days for the new development version 1.5.6, which will include this change. Thanks for pointing out this potential problem. It's still funny that it worked with R2.5.0 but not with R2.7.0, though.
