Hi Pedro,

That error means you are running out of memory. If you are using a
windows system, you may simply need to allocate more RAM to R by adding
--max-mem-size=<amount of RAM you have in megabytes>M to the target
field for your R shortcut. For instance, I have 2 Gb RAM, so I have
--max-mem-size=2000M.

If you are on some unix-type system (including Mac OSX), then you
simply need to get more RAM, or if that is not possible, try justRMA(),
which uses much less RAM.

Best,

Jim

Hi!
I am a new user of affypackage and limma.
When I run rma or mas in affy package I get the following messages:

Bacground correcting.....error=cannot allocate vector of size 75249kb
In addition:warning messages:
1: "multiget" is deprecated
use "mget" instead
2 Reached total allocation of 511B: see help (memory.size)

Anybody could give some advice ?
Thank you
