hi, When I was running ft_volumesegment, I got an error: cfg = []; cfg.coordsys = 'spm'; cfg.output = {'skullstrip' 'brain'}; seg2 = ft_volumesegment(cfg, mri_nom); the input is volume data with dimensions [256 256 256] Warning: adding W:\fieldtrip-20120125\fieldtrip-20120125\external\spm8 toolbox to your Matlab path Warning: Could not get change notification handle for remote W:\fieldtrip-20120125\fieldtrip-20120125\external\spm8\@nifti\private. Windows has exhausted its pool of handles for this file server. Type 'help changeNotification' for more info. > In path at 110 In addpath at 87 In ft_hastoolbox>myaddpath at 376 In ft_hastoolbox at 311 In ft_volumesegment at 154 performing the segmentation on the specified volume ??? Out of memory. Type HELP MEMORY for your options. Error in ==> flipdim at 38 y = x(v{:}); Error in ==> ft_volumesegment at 408 segment.anatomy = flipdim(segment.anatomy, k); You can get mri_nom if you read in (ft_read_mri the orig-nomask.mgz volume in /home/language/lilmag/grandaverage_mne). thanks for help.

Hi Lilla, it sounds like matlab was out of memory. What type of machine were you working on?

I created a test script with the actual data (test_bug1297) and copied the data to home/common. The test script does not reproduce the problem, it runs fine and reports having used 702MB of RAM for the computation.

Lilla, how much memory do you have? Can you run the "memory" command in MATLAB?

Lilla, do you think this is still a problem, and if not, just close the bug? JM (not Roemer)
