I think you might need a bigger computer. A run of that data set will require almost 1G, and there are places in the code where several data structures of the same size will need to exist simultaneously, so you can easily use 2 or 3 or 4 G to process a single run. In theory you could divide them up into smaller bits as long as you handle the stimulus schedule files properly.

Hi,

as I tried to show in the posting, I tried it on 3 Machines:

1. Linux, 1 GB memory: out of memory during OLS Residual Pass, then Java crashes
2. Linux, 2 GB memory: out of memory during Whitening
3. Mac (Mac OS X 10.5), 4 GB memory: as well: out of memory during Whitening

Thanks a lot & best regards,

Stefan Schadwinkel

How much memory do you have on that machine?

Hi,

I've got a general question about selxavg3-sess. In short, when I try to run the analysis, MATLAB exits with an out of memory issue.
