I just tried to run gcrma and got 30 warnings. I wonder if there are something I did wrong and if these warning affect my results. Thanks.

AH. GS==GeneSpring.
If you want to join them before importing to GeneSpring, you should do
this after computing expression values. You can do something like:
out <- rbind(exprs(exprSetA), exprs(exprSetB))
write.table(out, "Combined expression data.txt", sep="\t", quote=F,
col.names=NA)

Now, I tried to load the exported data from Bioconductor to GeneSpring
and found another question. Since I used U133 chip set, I wonder if I
can joint the U133A and B directly and import them to GS or I should do
probeset level normalization first (if so, which package in bioconductor
can do it) before joint them. Thanks.

you need to read in the type A and type B files into separate affybatch
objects.
eg
my.Data.A <-
ReadAffy(filenames=c("blahA1.cel","blahA2.cel","blahA3.cel"))
my.Data.B <-
ReadAffy(filenames=c("blahB1.cel","blahB2.cel","blahB3.cel"))

As I tried to write clearly in my last email about the upcoming

Hi all,
I'm trying to run an analysis on 24 Affymetrix HGu95v2 chips.
I've set up, via merge.AffyBatch, an affybatch object containing all 24 arrays.
A1 <- read.affybatch("A1.cel")
.
.
.
A24 <- read.affybatch("A24.cel")
A <- merge.AffyBatch(A1, A2)
A <- merge.AffyBatch(A, A3)
.
.
.
A<- merge.AffyBatch(A, A24)
I then computed MAS5 type Present/Absent calls for each array using mas5calls.
A.calls <- mas5calls(A)
p.a.A <- exprs(A.calls)
What I'd like to do now is remove all of those genes without a single present call across all 24 arrays before normalizing.
I can use the p.a.A file to obtain a list of the gene names/affy id tags that I want to remove but I can't figure out how to delete the relavent probe pairs from my affybatch object.
In fact that only things I've been able to find on the mailing list archive and/or vignettes are how to subset by array or how to remove chunks from the cdf environment - but this presents me with two problems, first I'm not sure I can get the pattern matching working well enough to identify which entry numbers in the cdf file correspond to the gene list I have, and secondly, people have already commented that this isn't neccessarily a sensible approach for proper analysis anyway. So I'm kind of stumped now!
Any help or advice would be most greatfully received,
many thanks,
Stu

I think you can argue that the batch methods (rma, gcrma) require more
than a certain number of chips to accurately estimate the parameters you
are modeling. However, this probably only applies to genes that are not
changing that much, so you will still see the ones that really change.
I don't think mas5 is affected by the number of chips.

Dear BioC
Are rma/gcrma/mas5.0/ etc limited by a minimum number of chip (.cel)
files?
I am calling expression values on a dataset with only 2 chips
(treated/control, pooled RNA from n=5). Is 2 chips too few .cel files
for
these methods?
Thanks for your help

This is really only a problem for the package maintainer. Your results
are not affected.
Basically there has been a change in R, and siggenes has not been
modified to account for that change. Right now everything is still
working correctly, you just have a bunch of annoying error messages.

Hi,
I am using siggenes package and I am encountering problems with warning
messages with the function sam.
For example, if I type :
res<-sam(data,3:11,12:88,B=1000,alpha.s0=seq(0,1,0.02),factor.s0=1.4826,delta.fdr=(1:10)/10,rand=123,vec.lambda.p0=(0:95)/100,ngenes=NA,iteration=10,initial.delta=(1:20)/10)
I've got as result the SAM analysis and the following answer:
Warning messages :
1:multi-argument returns are deprecated in :
return(r,s,r.perm,s.perm,Z,mat.samp,var.0.genes,NA.genes)
2:multi-argument returns are deprecated in :
return(alpha.hat,s.zero,cv,cv.zero)
3:multi-argument returns are deprecated in :
return(p0,spline.out,vec.p0)
4:multi-argument returns are deprecated in :
return(tab.fdr,mat.fdr,p0)
5 :multi-argument returns are deprecated in :
return(d,d.sort,s,d.bar,d.perm,mat.samp,s0,FDR,p0,fdr.ngenes,
I installed the R.1.8.1 version.
Could you help me ?
Thank you

This is a very good question that I have also been puzzling over. It seems
useless to try
tests of equality of the distribution such as Kolmogorov-Smirnov- due to
the huge sample size you
would almost certainly get a significant result.
Currently, I am using the following graphical method:
1. I compute a kernel density estimate of the combined data of all probes
on all the arrays.
2. I compute a kernel density estimate of the data for each array.
3. I plot both smooths on the same plot, and decide if they are the same.
Looking at what I wrote above, I think it would be better in steps 1 and 2
to background correct and
center each array before combining. It might also be between to reduce the
data to standardized scores before combining, unless
you think that the overall scaling is due to your "treatment effect".
It seems like half of what I do is ad hoc, so I always welcome any
criticisms or suggestions.

I would like to make a mixed environment for the mouse U74B (and C separately) version 1 and 2 chip set using common probesets. I know Ben Bolstad has built such a mixted environment for the U74 A chip. How do you do this? There are 5 library files for each chip. Do I have to create new library files containing only the common probesets and then using the make.cdf.package?
I would be grateful for suggestions on how to proceed.

The rownames of HGU-133A and HGU-133B are not unique (there is about 100+
redundancies). You might want to add these codes before rbind() to avoid any
confusion later.
A <- exprs(exprSetA)
rownames(A) <- paste("A.", rownames(A))
B <- exprs(exprSetB)
rownames(B) <- paste("B.", rownames(B))
Also, doing normalization before summary is better because we have more
information to utilize at probe level.
