Dear list:

I have a question in using "rma" or "mas5". After using them, I can
use "exprs " to get the intensuty fir each gene. Here my question is "how
can I get the Pvalue of the intensity for each gene?" Sometime, it's called
"present when Pv<0.05"; "absent when Pv>0.05".

Can exprs give me pvalue in some way?

The following are my codes:

DataA.4repli = ReadAffy(filenames = c("tar18.cel","tar19.cel","tar20.cel","
tar21.cel","tar22.cel","tar23.cel","tar24.cel","tar25.cel","tar26.cel","
tar27.cel","tar28.cel","31tar12.cel","31tar13.cel","31tar14.cel","
31tar15.cel","31tar16.cel","31tar17.cel","31tar18.cel","31tar19.cel"),phenoData
= matrix.A, verbose = TRUE)

esetRMA.basic.anova <- rma(DataA.4repli)#

esetMAS5.basic.anova <- mas5(DataA.4repli)

exprs(esetRMA.basic.anova)
exprs(esetMAS5.basic.anova)
se.exprs(setMAS5.basic.anova)


Thank you in advance.
