Hi,
Wonder if anyone has input on this problem. I have quite a number of
genes having the same expression across replicates, which i assume may
cause difficulty in calculating std. error for pairwise.comp (t
tests). As i went through previous archives, i am under the impression
the version 1.2.3 should fix the problem. Or is there more recent
release up there that goes around this error?
thanks.
J.

Hi:I would like some suggestion on how to go around thefollowing error
with simpleaffy:Using:R 1.9.0simpleaffy 1.2.3Code:rawdata <-
read.affy(covdesc="covdesc.txt")rma <- rma(rawdata)pw.ua <-
pairwise.comparison(x=rma, group="treatment",members=c("u", "a"))Error
in get.fold.change.and.t.test(x, group, members,logged = logged, :
a or b too big or not enough iterations inbetacfI got this error
initially with a lower version (1.09)of simpleaffy, and then upgrade
it to 1.2.3, assuggested in one of the archived email. But the
