I'm trying to normalize some data gotten from GEO with the R affy package. i have taken 12 ovarian cancer sample from GSE14407 and 1 normal sample from ovary from GSE2361 and normalize these data by applying rma alogorithm:
"GSM44674.CEL does not seem to have the correct dimensions"
A quick look at your GEO sets, tells me that both sets did not use the exact same platform. Might that be the problem?
plz give me probable solution.
Use only arrays together that were all done on the same platform.
what is your exact code ?
my code is: library(affy) norm <- ReadAffy() norm.rma <-rma(norm)
