Same code for different versions of the same platform

Question

[Joe Kherery]

I would like to use the R code that I wrote to analyze affymetrix human genome u133 plus 2.0 array to analyze Affymetrix Human Genome U219

I would like to know if I can use the same code for different versions of the same platform;

library(simpleaffy)
celfiles <- read.affy(covdesc="phenodata.txt")
celfiles.rma <- rma(celfiles)
samples <- celfiles.rma$Target
samples
samples <- as.factor(samples)
design <- model.matrix(~0 + samples)
colnames(design) <- c("control","disease")
library(limma)
fit <- lmFit(exprs(celfiles.rma), design)
contrast.matrix <- makeContrasts(disease-control, levels=design) 
fit.con <- contrasts.fit(fit, contrast.matrix)
fit.eb <- eBayes(fit.con)
probeset.list <- topTable(fit.eb, coef=1, number=50000, adjust.method="BH", lfc=1.5)

Try it and find out.

Dear YaGalbi, OFC I tried this before posting here. And yes it worked, but I'm not sure if there's something missing from the code that is needed in another version of the same platform.

Don't they publish a manifest or other document schema for each release? That would help confirm or disprove fears.

[Joe Kherery]

Dear, Alex Reynolds They did not publish supplementals to compare.

I'm surprised there is no schema for the documents they put out. Especially from a commercial entity. If things don't work, I guess all you can do is try to reverse-engineer the data format.
