I generated a segementation of a 3-D pixel array using the MATLAB Volume Segementer tool for a relatively large file (>2 GB). I now want to save it as a .mat file . Unfotruantely, from what I can tell, the VolumeSegementer apps automatically saves using the default .mat file type, which can't handle files this large. Normally I would choose the 7.3 version fo the .mat file for these larger images, but I am unsure how to do that with the VolumeSegmenter tool.

I was able to find workaround, but a "better" answer would be appreciated.

I saved the labels as a workspace variable called 'data.mat' (the label was 'data') which I then saved using the command window via:

save('data.mat','data','-v7.3')

This isn't ideal as my data sizes run up agaisnt the RAM of my machine, and adding extra variables to my workspace is to be avoided (why I am saving as .mat files in the first place).
