When I use tkmedit Diff01 orig.mgz frontal_rh.nii.gz I have this error.Error: Loading Surface frontal_rh.nii.gz Couldn't load the surface. Tkmedit couldn't read the surface you specified. This could be because the file wasn't a surface type that tkmedit recognizes or the file was unreadable due to permissions. I do not visualize the mask on T1, neither by tkmedit. It seem that they have different dimension. thanks ----Messaggio originale---- Da: greve(a)nmr.mgh.harvard.edu Data: 5-set-2013 1.25 A: <stdp82(a)virgilio.it> Cc: <freesurfer(a)nmr.mgh.harvard.edu> Ogg: Re: R: Re: [Freesurfer] R: Re: R: Re: R: Re: R: R: Re: Mask from cortical parcellation The orientation looks right to me, ie, the little letters on the side that indicate direction are correct.

I'd like to perform probtrackx (FSL) from seed (subcortical) to target (cortical) masks. To this aim, I should trasform all cortical and subcortical masks obtained by FS on MNI space. Therefore, firstly, I'd like to overlay the masks that I obtained by mri_binarize on the structural image to check the masks. Next, I'd like to apply FLIRT to trasform all masks in a common MNI152_1mm space. My problem is " which is the T1.nii.gz that can I use to overlay the cortical masks created by mri_binarize?"

Tracula threshold path
by celine＠nmr.mgh.harvard.edu 04 Sep '13

04 Sep '13

Dear experts, I read some previous answers about the thresholding of the paths obtained after tracula process, but I am not completely sure I had the right answer. I will need to get an roi from a path for example the cortico-spinal tract that will be consistent amongst patients. I will further use this roi to calculate the lesion volume (my subjects are patients with MS) within a specific path. My question is: is the path.pd.nii.gz file already threshold or should I threshold it to a specific value? If I use the same threshold for each subject for example at 10% of the maximum value, will I obtain an ROI that is consistent among subjects or is is possible that I would get a very thin CST in some subjects, or a very wide cst for example? Thanks for your help Celine -- Celine Louapre, MD Research Fellow at Massachusetts General Hospital Department of Radiology, MGH Building 149, Room 2301 13th Street Charlestown, MA 02129

Improving the accuracy of average surfaces made from make_average_subject
by Miggy Chuapoco 04 Sep '13

04 Sep '13

Hi all, I'm trying to make a group average of a set of subjects that we've collected various functional data on and use anatomical landmarks of the group average surface to predict the locations of functional areas that we've found to be correlated to the anatomy of the ventral cortex. As such, we'd like to get as accurate of an average surface as possible. I've come up on two problems that I'd like to address and was wondering if anyone could help come up with a solution. I ran the recon-all command on all the subjects and created a segmentation, however we made edits to the segmentation using ITK-SNAP, and not tkmedit. Some of the changes were fairly drastic and we'd like to use the fixed segmentations in the averaging process. I've considered perhaps running the -autorecon2-wm flag, but unfortunately using ITK-SNAP essentially makes edits to ribbon.mgz, and not wm.mgz. I was wondering if there was a way to "extract" a new wm.mgz from an edited ribbon.mgz. My second problem involves trying to anchor a sulcus on the ventral surface during the averaging process (the mid-fusiform sulcus) in hopes of getting a more accurate representation of the sulcus on the average surface. As it stands there is a bit too much variability of the average MFS location when compared to the individual subjects' MFS location, and we'd like to reduce that if possible. Is there any way of using a label, or something similar, that can be considered as an "anchor" during the averaging process? Thanks and regards, Miggy Chuapoco
