That's almost right. Just specify the subject name and not the full path.

Hippocampal subfilelds label
by Shashwath Meda 31 Aug '11

31 Aug '11

Hi Koen - I am looking at some hippocampal subfield measures on 3T and 7T and noticed that there is a label called "hippocampus" from your recent publications it was unclear what this label exactly meant? Is this a useful subfield measure to be considered for further analysis? What does this particular segment represent? Thanks, Shashwath Meda

Re: [Freesurfer] Freesurfer surfaces in the original space
by Douglas N Greve 31 Aug '11

You'll need to do this in steps. 1. Create a registration matrix R between your axial and conformed data: tkregister2 --mov axial.nii --targ orig.mgz --regheader --reg axial.reg.dat --noedit --s subjectname 2. Get the tkreg vox2ras matrix T from your axial: mri_info --vox2ras axial.nii 3. Compute a new matrix M = inv(T)*R. Put it into a file with the same format as axial.reg.dat (call it axia.crs.reg.dat). Just replace the 4x4 matrix. 4. Convert the surfaces with mri_surf2surf, something like mri_surf2surf ---hemi --subject subjectname --sval-xyz lh.white --reg axial.crs.reg.dat --tval lh.white.axial.crs --tval-xyz doug Navid Shiee wrote: > Hi, > > I need coordinates in col-row-slice space of my axial data.

Hi all, I don't understand what's wrong with this command line: mri_surf2vol --surfval .curv --hemi lh --fillribbon --template orig.mgz --outvol curv-orig.mgz I tried also to use: mri_surf2vol --surfval .curv --hemi lh --fillribbon --template orig.mgz --outvol curv-orig.mgz the error is always the same: cannot recognize the type .curv (or curv). Where is the problem? Thanks, -- Antonella

Re: [Freesurfer] Freesurfer surfaces in the original space
by Douglas N Greve 31 Aug '11

Hi Navid, it is still not clear what you want. Each surface coordinate has an xyz. This space that this xyz is in is a peculiar space defined by FS. You want to use a different xyz space. It could be scanner space. It could be col-row-slice of your axial data. Or is it that you just want to visualize the surfaces on the axial. In that case, you'll have to indicate what tool you are going to use (you cannot use tkmedit for this -- it will just conform it to 256^3). doug Navid Shiee wrote: > Hi, > Thanks for your reply.
