Hi Expert, I am trying to extract timecourses from AAL ROI's. I have tried building my own and used the downloaded file marsbar-aal-0.2 from this site. This is the error I receive when trying to extract the data from .nii files: ??Mapping files : ...done Fetching data : 1/1 Output argument "vXYZ" (and maybe others) not assigned during call to "maroi/getdata". Error in maroi/get_marsy (line 76) [y vals vXYZ mat] = getdata(o, VY); Error in marsbar (line 990) marsY = get_marsy(o{:}, VY, sumfunc, 'v');...
