how much memory does your machine have? How many files are there in
"myfilenames" and what chiptypes are they? You might get started with
using fewer arrays; on the long run, getting more memory seems like a
You can also try the justGCRMA (package gcrma) and justRMA functions:
The man page says:
This method should require much less RAM than the conventional
method of first creating an 'AffyBatch' and then running 'gcrma'.
> Hi Group,
> Iam a beginner in learning R and Bioconductor.
> I have a basic question.
> How can I increase the memory limit.
> When I type the command:
> abatch <- ReadAffy(filenames = myfilenames , phenoData = mypheno)
> It throws me this error:
> Error: cannot allocate vector of size 625759 Kb
> In addition: Warning message:
> Reached total allocation of 511Mb
> How can I overcome this?
