[Freesurfer] check Talairach registration using Freeview

Hi there, I have two questions regarding Talairach registration. _*Question 1:*_ I would like to check Talairach registration according to this page: https://surfer.nmr.mgh.harvard.edu/fswiki/FsTutorial/Talairach_freeview I see this line for the tutorial: freeview -v tal_before/mri/T1.mgz

[Freesurfer] help with mris_make_face_parcellation

Hi, I’m interested in using mris_make_face_parcellation, but I can’t find any documentation on the input arguments and outputs. Could you give me more information on this command or direct me to the proper website? Thanks, Sophie -- Sophie Wohltjen Post-baccalaureate Fellow Laboratory of Brain

Re: [Freesurfer] Question about the outputs of recon-all

it is hard to say that they are in the same space. To be in the same space, they have to have the same origin, direction cosines, and voxel size. Likely your functional results are in MNI152 whereas fsaverage is in MNI305. There is no such thing as MNI space per se. If this is the case, I

[Freesurfer] Brain on a Single Sphere

Hello Experts, Is there any command that can map both hemispheres of the brain into one single sphere? It will be equal to combining two inflated hemispheres into one spherical brain surface that has its own scalar overlays. Best, Saeed ___ Freesurfer

Re: [Freesurfer] selxavg3-sess, -svres

Hi Doug, thanks for the response. The residual from unwhittening data is the same as those produced by the full model. One more question. I transferred the functional data from functional space to the anatomical space using mri_vol2vol without resample: mri_vol2vol --reg register.dof6.dat

Re: [Freesurfer] selxavg3-sess, -svres

They are not the same. As you point out they have a correlation of .98, not 1.0. What you are discovering is the inconvenient truth that task signal accounts for a very small proportion of variation. Welcome to fMRI:). I think the reason why the residual does not equal y - X*beta is that they

Re: [Freesurfer] visualizing paths stats by voxel

Hi Janosch - Looking at the stats files of your subjects, just by a quick count of the number of lines, I see that there are some subjects that have only 1 time point and some that have multiple time points, and that the pathstats.byvoxel.txt files have different lengths between those two

I would probably use bbregister to register the volumes, then use mri_surf2surf with the --reg option to map the surfaces from one space to another. On 8/14/15 1:59 PM, Hibert, Matthew Louis wrote: Hi Bruce, My goal is to compare the surfaces and segmentations from the reconstructions of
