Dear list,
I'm trying to normalize using threestep several CEL files (around 100 
CEL files). I got the following error:

Error: cannot allocate vector of size 6.5 Mb

I've been reading the suggestions about this error in the mailing list, 
but I couldn't fix it. My system (Win XP Prof, 32 bits) has 3 GB RAM and 
I did the following:

    * I used the command line --max-mem-size=3071M in the R shortcut
    * I changed the boot.ini file to allow up to 3GB
          o [boot loader]
            timeout=30
            default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
            [operating systems]
            multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft
            Windows XP Professional" /3GB /noexecute=optin /fastdetect
    * I try to remove not used variables using the rm() command and the
      garbage collector gc() within the source code.

But, even with those changes, I'm still running out of memory. It is 
strange, because, having a look at the tasks administrator, R doesn't 
use more than 1600 MB and the whole system never goes further than 2GB

Any other tips?
Thanks,
Javier
