Re: [Freesurfer] Repost: Make liberal ROI masks

Hi Martin, I am a little confused. Can you explain a little more about what you need? Do you want the freesurfer cortical ROIs dilated into the surrounding regions like white matter and CSF or something? If so, then Doug's suggestion sounds reasonable. In the case of my parcellation, I ran the MN

can you run mris_info on /scratch/lfs/aoshea/testAndrew/dotsonFSprocessed//EX03/surf/rh.white and/or view it in freeview to make sure it isn't corrupted? On Wed, 15 Jul 2015, O'Shea,Andrew wrote: Hello all, I am having an issue where the mris anatomical stats command is failing and only prin

Dear Thomas and Doug, Thanks a lot for your replies, I believe you fully answered my question. @Thomas: The reason I would like to dilate masks into white matter is that although the masks are quite accurate for structural volumes, the functional data doesn't perfectly fit the structural (even wh

Hello all, I am having an issue where the mris anatomical stats command is failing and only printing 'segmentation fault' instead of the expected volume, area, thickness, etc. This is happening for ~20% of the subjects, but seems to work fine for the remaining 80%. All labels were created and ma

I tried loading the label and surfaces in free view and everything looks normal to me. This is the output I get with mris info: [aoshea@gator1 ~]$ mris_info /scratch/lfs/aoshea/testAndrew/dotsonFSprocessed/EX03/surf/rh.white SURFACE INFO type: MRIS_

SPM does not make any distinction about the source of the data. For SPM to work, all you need is .nii files for your data and you'd need a VOI.mat that corresponds to the .nii file size. If you take a look at the gPPI toolbox on the NITRC website, there are commands/tools that convert FS-FAST 1st
