Hi Tapsya, it looks like your data are going to require about 12G of memory due to an inefficient use of memory by selxavg when there are so many time points across a run (I've never tested it with 6570 total time points!). If you want to run this on launchpad, then you'll need to request that much memory when you launch the job.

Dear FSFAST,

I am using the program selxavg3-sess on 3D data for a single session (i.e. selxavg3-sess -s avml07 -analysis $ana_vol -force) and it errors out with the following message:

OLS Residual Pass run 1 t= 0.0 ??? Error using ==> unknown Out of memory. Type HELP MEMORY for your options.

Error in ==> fast_selxavg3 at 469 rho1run = sum(rrun(1:end-1,:).*rrun(2:end,:))./rsserun;

I am using FSFAST v 5.1. My analysis uses FIR design, 6 runs in each session with 18 contrasts. I executed the program on clusters 'launchpad' (@ Martino's center) and allocated 49GB to it.

My question is how much CPU and memory you recommend I should allocate? I have also attached the log file in this email.

Any help is greatly appreciated!

Thanks.

Wishes, Tapsya
