Dear FS-experts, I'm trying to follow the instructions on http://surfer.nmr.mgh.harvard.edu/fswiki/VolumeRoiCorticalThickness to get volumetric stats etc on a functional ROI derived from marsbar. The tutorial looks all clear to me, however, I have already problems at the first step.
If I want to view the ROI I see a big orange square instead of the specific region. This almost fills the whole brain. command: tkmedit -f avg152T1.nii -overlay DLPFC.nii -fthresh 0.5 I created the DLPFC.nii in MarsBar (v. 0.42): "ROI definition" > "Export" > "Export ROI to image" (select: DLPFC_roi.mat) > from image (select: avg152T1.nii) > save as DLPFC.nii If I view the ROI on marsbar it looks good. Did I miss some prior step, or is something else wrong? Thanks in advance! Best wishes, Cédric ------------------------------------------------------------ P.C.M.P.
