Hello all!
I have 16 Affy Hg-U133plus2 cel files that I am trying to analyze. I
am
having difficulties generating expression data because of memory
problems. I am working on a Dell desktop running WinXP. I can
successfully generate expression values if I use "RMA" but if I try
MAS5
or GCRMA or LiWong instead then I consistently get an error message
with
"Cannot allocate vector of size 169362 Kb." To try to increase
available memory I have already done two things: (a) I right-clicked
on
the R icon and changed the box labeled 'Target' to read "C:\Program
Files\R\R-2.2.0\bin\Rgui.exe" --sdi --max-mem-size=2000M" and (b) I
have increased the virtual memory Total Page File size to 2000MB. But
it still runs out of memory.
Help! Any suggestions -- I don't really have access to any bigger
computers?
Thanks.
