Dear all,
I want to obtain the Standard Error of the signals given by RMA. I can do
this with the se.exprs() function after performing the expresso() function
on my data.
My problem is that this does not work on a large number of arrays (n=111),
because I cannot even read the data; I have the following:
-------------------------------------------
> raw <- ReadAffy()
Error: cannot allocate vector of size 439615 Kb
-------------------------------------------
even if I maximize the memory available for R to run with the line:
--max-mem-size=3000M
So my question is: do you know another way for me to obtain the SE of the
given signals by RMA ?
Thanks a lot for your help,
Florence.
