Re: [Freesurfer] Extracting White Matter Structures without using Tracula
Hi Bruce, Our main concern is that we will be incorporating additional sources of error by doing so! But it seems there is no way to get around it. Thanks for the prompt response!

[Freesurfer] Extracting White Matter Structures without using Tracula
Hello Freesurfer experts, I am looking to extract certain white matter pathways (for instance, the superior longitudinal fasciculus, uncinate fasciculus) with freesurfer which I believe are affected by Alzheimer's Disease. But it seems that these can only be obtained by performing tractography using Tracula. I was wondering if there was some other way to obtain the labels for these structures without having to do so? Thanks in advance.

[Freesurfer] Basal Ganglia Segmentation
Fear Freesurfer Experts, I have a feeling this question has been asked already but I'm still confused about it. Is there a way to extract the basal ganglia structure using freesurfer?

[Freesurfer] Segmentation fault using mri_label2vol
Hello Freesurfer experts, I'm getting a segmentation fault when I use the mri_label2vol command to push aseg labels from freesurfer space to my subject's original T1 space (using the example given on the freesurfer website). I'm not sure why this is happening...I've tried changing the parameters countless times but nothing has worked. I also checked my "aseg.mgz" to make sure it's not corrupted but that isn't the issue either. Any help would be highly appreciated!! Thanks in advance mri_label2vol --regheader /scratch/o/olegm/olegm/2015/test_waj/aseg.mgz --seg /tmp/tmpUj4qzA/aseg2raw/aseg.mgz --temp /scratch/o/olegm/olegm/2015/test_waj/rawavg.mgz --o /tmp/tmpUj4qzA/aseg2raw/aseg_vol.nii.gz Number of labels: 0 Annot File: (null) Template Volume: /scratch/o/olegm/olegm/2015/test_waj/rawavg.mgz Outut Volume: /tmp/tmpUj4qzA/aseg2raw/aseg_vol.nii.gz Registration File: (null) Fill Threshold: 0 Label Vox Vol: 1 ProjType: (null) ProjTypeId: 0 ProjStart: 0 ProjStop: 0 ProjDelta: 0.1 Subject: (null) Hemi: (null) UseNewASeg2Vol: 1 DoLabelStatVol 0 LabelCodeOffset 0 setenv SUBJECTS_DIR /scratch/o/olegm/olegm/subjects $Id: mri_label2vol.c,v 1.34.2.5 2012/06/08 17:31:03 greve Exp $ Template RAS-to-Vox: -0.985 0.000 0.000 128.000; -0.000 -0.000 -0.985 128.000; -0.000 0.833 -0.000 98.000; 0.000 0.000 0.000 1.000; Template Voxel Volume: 1.23773 nHits Thresh: 0 Computing registration based on header RegMat: 1.000 0.000 0.000 -0.000; 0.000 1.000 0.000 0.000; 0.000 0.000 1.000 0.000; 0.000 0.000 0.000 1.000; Label RAS-to-Vox: -0.985 0.000 0.000 128.000; 0.000 0.000 -0.985 128.000; 0.000 0.833 0.000 98.000; 0.000 0.000 0.000 1.000; ASeg2Vol: Building LUT Segmentation fault ___ Freesurfer mailing list Freesurfer@nmr.mgh.harvard.edu https://mail.nmr.mgh.harvard.edu/mailman/listinfo/freesurfer The information in this e-mail is intended only for the person to whom it is addressed.
