WARNING: tcsh v6.17.06 has an exit code bug!
by Andrew Bock 30 May '13

30 May '13

Hello everyone, I just updated to Freesurfer 5.3.0, my OS is Ubuntu 12.04. When I run 'recon-all -i <T1 image> -subjid <subject name>' I receive the following error: WARNING: tcsh v6.17.06 has an exit code bug! Please update tcsh! The directory structure appears to be set up correctly, and the command finishes without error. I do not receive this error when using Freesurfer 5.1.0. I have yet to run 'recon-all -all -subjid <subject name>' in 5.3.0. Any ideas on what produces this error? is it safe to ignore? Thanks in advance, Andrew

Re: [Freesurfer] mris_divide_parcellation color table error

I am running version 5.3- the latest version. I also tried running the codes on v5.0 and got the same result. Is there any way I can change the color table so that the colors of the parcellation are unique?

Exporting surface coordinates to Nifti header space
by schreibm＠informatik.hu-berlin.de 30 May '13

30 May '13

Hi Freesurfers! I'd like to load my original Nifti T1 image data (subject.nii) and the wm/gm-surface coordinate data (for instance lh.pial) in matlab as vectors in the same coordinate system. If I do it in the naive way, i.e. [x,y,z,1]=[i,j,k,1]*sform' for the Nifti coordinates resp. freesurfer_read_surf(...) for the surface nodes, then surface and Nifti appear not to be coregisterred. It looks as though there would be a spacial shift missing. Although having tried several matrices I cant figure out which is the one to choose. Inspecting the Data by Freeviewer I observe the same spacial shift, inspecting it by 'tkmedit subject_id brainmask.mgz lh.pial' everything is fine. Could you tell me, which transform I have to apply to the surface coordinates? That would be really nice. Thanks and best Regards, Max

volume and mean value of a custom made white matter ROI
by Subhabrata Chaudhury 30 May '13

30 May '13

Hello Everyone, Greetings. I am learning freesurfer tricks. I am stuck and have a question. I have run 10 subjects through freesurfer. I have made custom volume regions for arcuate fasciculus for 10 subjects. Now I want to get some measurements inside this region. How do I get the volume of the region ? How do I get the mean T1 intensity in this region ? Can somebody share some script or point me to some script ? Will be very thankful. Subha

error loading volume brainmask.gcut.mgz
by Claudia Dacquino 30 May '13

30 May '13

Hi Freesurfers, I'm trying to remove some dura which affect my surfaces with the command recon-all -skullstrip -clean-bm -gcut -subjid but then I can't use tkmedit to check that. The message I get is: Error: Loading volume brainmask.gcut.mgz Couldn't read the anatomical volume. Tkmedit couldn't read the volume you specified. This could be because the image format wasn't recognized, or it couldn't find the proper header, or the file(s) were unreadable, or it was the wrong size. Actually I did check in brainmask.gcut.mgz directory properties, and I saw the size of image is something like 150 KB, instead of 1 MB like is brainmask.mgz. What is the problem? Thanks, Claudia

Problem with recon-all
by Andrea Tateo 30 May '13

30 May '13

Dear FS experts, I have a problem with the command "recon-all". In many cases when I use it on the same brain's MRI, on the CLUSTER COMPUTING INFRASTRUCTURE, about 40% of my jobs finish without erros while the other are killed at the command "nu_currect", as you can see from the file.log in attachment. Do you have any suggestions? Thanks a lot for your help. Best regardes, Andrea
