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

mris_divide_parcellation color table error
by Tina Jeon 29 May '13

29 May '13

Hello freesurfers, I am trying to create a figure similar to the Hagmann et al 2008 paper with 998 rois overlaid onto the surface, however, I am finding that there is no random, unique color for each parcellation unit like described in the help file for mris_divide_parcellation. I have attached a snapshot of my annotation file overlaid onto the surface, as you can see, the color iterates the same/similar color for a particular label. Can you tell me what I am doing wrong? Is there a pre-existing atlas as described in the Hagmann paper? My input: mris_ca_label -t ./FreeSurferColorLUT.txt subject_name lh ./lh.sphere.reg $FREESURFER_HOME/average/lh.curvature.buckner40.filled.desikan_killany.2010-03-25.gcs ./lh.aparc.998rois.annot mris_divide_parcellation subject_name lh ./lh.aparc.998rois.annot ./splittable.txt ./lh.annotation.998rois_26.annot Many thanks, Tina Jeon, MS UT Southwestern Medical Center '14 ________________________________ UT Southwestern Medical Center The future of medicine, today.

no hippocampal stats despite running FS 5.3 with -hippo-subfields
by Salil Soman 29 May '13

29 May '13

Dear Freesurfer Experts, I have been running freesurfer 5.3 without any reported errors using the following command: recon-all -i SPGR/*.gz -s SUBJECTIDENTIFIER -nuintensitycor-3T -nocanorm -openmp 50 -hippo-subfields -all However, when I look for any of the hippocampal subfield stats (as described on http://ftp.nmr.mgh.harvard.edu/fswiki/HippocampalSubfieldSegmentation) I do not find any of them. Any suggestions on what I am doing incorrectly? Best wishes, Salil Soman, MD, MS
