Sorry that is actually a FSL bug that I have already reported to them. You can work around it with (/bin/sh -c '. /usr/local/fsl/etc/fslconf/fsl.sh; fslmaths filtered_func_data -sub filtered_func_data -add filtered_func_data_clean filtered_func_data_clean’)

The total swap space that is available is approximately 130GB whereas the total amount of RAM is just as much, that would seem to me to be plenty enough. What other suggestions do you have? How important is the FSL call (/bin/sh -c '. /usr/local/fsl/etc/fslconf/fsl.sh; fslcpgeom filtered_func_data filtered_func_data_clean') ? Even though the command does not complete I can still open it with fsleyes and fslinfo without issue. From my brief research into fslutils fslcpgeom copies header information. Can I perhaps comment out that command so the cleaned dtseries file can be generated (the following lines of code)? -Tim Timothy Hendrickson Neuroimaging Analyst/Staff Scientist University of Minnesota Informatics Institute University of Minnesota Bioinformatics M.S.

If not, you will need the compiled matlab to be up to date with the matlab scripts, and use mode 0. The alternative, figuring out how to build octave to handle larger matrices, sounds like an adventure.

What is the number of timepoints and number of voxels of your concatenated input? Are you trying to run more than one subject at once on the machine? I believe the way we are approaching multi-run fix is that we only concatenate scans that were taken on the same day.
