Hi Katarina it looks like that file might be corrupted. Where did you get it from? Can you view it in freeview? Maybe that partition was full when you copied it there or something similar? cheers Bruce On Mon, 31 Aug 2015, Katarina Trojacanec wrote: Dear experts, After running recon-all

Yep, that did the trick. I found an archived post where someone had a similar issue. Thanks. Michael Amlung, Ph.D. Assistant Professor Department of Psychiatry and Behavioural Neurosciences DeGroote School of Medicine McMaster University Peter Bor

Re: [Freesurfer] MRITOTAL

Dear Bruce and ​Jürgen, Now I see something important which may help solving the problem. I have 31 PCs in my lab and all of them are installed with UBUNTU 14.04. 30 PCs were able to process all 47 subjects successfully. But failed to process the remaining 8 subjects. Fortunately, one PC is insta

[Freesurfer] Thalamic sub-nuclei

Dear all, I am interested in analyzing thalamic sub-nuclei separately, instead of the whole thalamus. I've noticed that in the FreeSurferColorLUT.txt file there are some labels that correspond to thalamic sub-nuclei (Labels #No. 8001-8014). However, I do not find those labels in my aparc+aseg

Hi Cristina sorry, while thalamic nuclei are of interest to us we haven't developed anything for labeling them yet. cheers Bruce On Mon, 31 Aug 2015, Lois Gomez, Cristina wrote: Dear all,   I am interested in analyzing thalamic sub-nuclei separately, instead of the whole thalamus. I've

[Freesurfer] converting ROI .label to MNI space for SPM8

Forgive me, but I'm re-posting my query below hoping someone will respond this time around. Thanks in advance! Dear Freesurfers, I'm hoping you can help me resolve an issue I'm having with regard to converting my ROI labels from freesurfer space (Taliarach) to MNI space in prep for using these

Re: [Freesurfer] converting ROI .label to MNI space for SPM8

I'm not sure what is going wrong, but I would use mri_label2vol directly instead of using the combination of mri_convert and tkregister. Instead of passing it a registration file, use --regheader brainmask.mgz On 8/31/15 5:26 PM, Emma Thompson wrote: Forgive me, but I'm re-posting my query b

Marie, Yes, I'm getting this error for all subjects. Unfortunately, I'm unable to send you any of our subjects to look at. You've helped in identifying that our ROIs are not getting saved, though. Do you have a guess as to why that might be? Otherwise, we'll have to figure out why they're not

Thank you for the quick response. I wanted to create volume has the following dimentions in mm ( 6.25 X 6.25 X 7.5) in a position where the coordinates (in mm) are X=-15 Y= -4 Z= 13 is this command line correct: mri_volsynth --dim 6.25 6.25 7.5 1 --c_ras -15 -4.3 13 --o voxel.nii   Bests, John

Re: [Freesurfer] Did not find any volume geometry information in the surface

Eric, It will be easier to help, if you provide a much more detailed description of what you did: the full command line, the version of freesurfer, and all terminal output (http://surfer.nmr.mgh.harvard.edu/fswiki/BugReporting this may help). hth D On Mon, Aug 31, 2015 at 3:27 PM, Erik Lindberg

Re: [Freesurfer] mri_volsynth

No, you will need to decide how big you want your voxels to be. If you use --volres 1 1 1 1 then that should work. It will put the center of the volume at that coordiate. If you want a single voxel, then use --dim 1 1 1 1 and --volres 6.25 6.25 7.5 1 On 8/31/15 7:52 PM, John Anderson wrote:

sorry, --res (not --volres). res is the voxel size (volume resolution). dim is the number of voxels in each dimension On 8/31/15 10:16 PM, John Anderson wrote: Thank you! Actually when I run mri_volsynth --help I can't find --revol. is it the same flag --res? also what is the relationship betwe
