For each point along a tract (and not just the end points), it has a prior probability (that it has computed from the atlas subjects) that a tract goes through each of the aparc+aseg labels, or goes next to (in the L, R, A, P, etc direction) each of the aparc+aseg labels.

Hi Heidi - It's up to you. As long as the N of subjects at each point is included in the statistical test, this will adjust the corresponding p-value accordingly.

Hi FreeSurfer, I have analyzed my diffusion data using Tracula and combined the voxelwise diffusion measures across all subjects in one file (following the guidelines on the wiki). In this text file, I saw that for some of these voxels some people have NAs, so their tract is most likely shorter. I now would like to do t-tests for each voxel and plot these in freeview (as also suggested in the wiki). Would you recommend to only take those voxels that have a value in each subject to keep the number of subjects consistent at each voxel ? Look forward to your thoughts on this. Best wishes Heidi

bbregister problem with --init-best
by Feilong Ma 17 Mar '17

17 Mar '17

Hi FreeSurfer Developers, I'm having trouble using bbregister with the `--init-best` flag, a minimal example and error message is like this: $> bbregister --s ag00 --mov data/ag00/align/raiders/run00_ref.nii.gz --init-best --bold --lta data/ag00/align/raiders/run00_ref_to_anat.lta ERROR: cannot spec an init method with --init-best It seems `InitCoreg` is set to 1 by default in the code of bbregister. Therefore, when `--init-best` is also set, it would always trigger the conflict detection and exit with the error message. Here are some related version information: - FreeSurfer version: freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0-2beb96c - bbregister version: $Id: bbregister,v 1.75 2016/05/10 20:02:28 greve Exp $ - OS: CentOS Linux release 7.3.1611 (Core) Best, Feilong

subject directory
by Limachia, Gaurang (NIH/NINDS) [F] 17 Mar '17

17 Mar '17

Dear Freesurfer Experts, I want to customize the directory so I can run the following command mris_preproc --fsgd gender_age.fsgd --cache-in thickness.fwhm10.fsaverage --target fsaverage --hemi lh --out lh.gender_age.thickness.10.mgh However, after running this command it keeps checking in the wrong directory for the files. How do I change the directory, do I change it in the FSGD file I made or somewhere else? I ran the recon-all qcache, but I need to run this on the previously cached data. I would greatly appreciate it if you can assist me with this problem. Best Regards, Gaurang Shyam LImachia

need help clean up pial and wm surfaces
by padma 17 Mar '17

17 Mar '17

Hi, I’m trying to get pial and wm surfaces for a subject (who has some clinical wm related problems). They were imaged (T1-MPRAGE at 3T) at their imaging center not here at Martinos Center. The gray-white contrast doesn’t look as good as the healthy volunteers that I imaged in the 3T at the Martinos Center. My question is — I can’t figure out where to start repairing the subject’s pial and wm surfaces. I wonder if someone could suggest how to proceed. I’ve ftp/uploaded the freesurfer output to surfer.nmr (PT001_from_padma.tar.gz) Thanks for your help, Cheers, —Padma

registration for AD, MD and RD images
by Su, Shiran 16 Mar '17

16 Mar '17

Hi, FreeSurfer developers, I am trying to use the command 'bbregister' to register the axial diffusivity, mean diffusivity, radial diffusivity and FA maps to the segmentation result (get from the 'recon-all' command). The registration works well for the FA map. But for AD, MD and RD maps, the registration is a little off (as can be seen in the example). Although we could use the 'transform volume' tool (tkregister tool) to move the diffusion maps to make the map fit better with the segmentation surface, I am wondering whether this is a normal issue and we could only use 'transform volume' tool to modify them? Because our AD, MD, RD and FA maps are all masked and have good location correspondence with each other. If not, is there any method we could use to get a better registration result for the AD, MD and RD maps? i.e. [cid:3d37426c-cd99-4a42-a61b-d88da1cab2f9] [cid:599ee7ae-47c2-4675-99c5-b0c82ee7d8df] The registration works well for the FA map (left) but not for the AD map (right). Thank you! Best, Shiran Su

TRACULA and priors problem
