[Freesurfer] Problems with mri_label2vol

i want to convert the ".annot" files to nifti. When i used "mri_label2vol", I used this command mri_label2vol --subject fsaverage --annot $FREESURFER_HOME/subjects/fsaverage/surf/lh.ic3.annot --o test.img --hemi lh --regheader $FREESURFER_HOME/subjects/fsaverage/mri/brain.mgz --temp $FREESURFER_HO

Re: [Freesurfer] Question about if there is constant number of vertexes across different brains

Yes, we prefer keeping the sampling as uniform as possible in subject coordinates On Jul 24, 2011, at 12:10 PM, "Matt Glasser" wrote: > There are different numbers of vertices in subjects surfaces. It is > possible to resample subjects' surfaces to a common mesh after registration, > but the

Hi Knut Each brain will have a different # if vertices and faces. We normalize this when we map to fsaverage Bruce On Jul 24, 2011, at 12:07 PM, Knut J Bjuland wrote: > Hi I have read (Dale, Fischl et al. 1999) and (Fischl, Sereno et al. > 1999) . I have a question about if I understood the tes

Re: [Freesurfer] Question about if there is constant number of vertexes across different brains

There are different numbers of vertices in subjects surfaces. It is possible to resample subjects' surfaces to a common mesh after registration, but the FreeSurfer folks don't prefer this approach. They prefer to simply resample the quantitative data. Peace, Matt. -Original Message-

[Freesurfer] Question about if there is constant number of vertexes across different brains

Hi I have read (Dale, Fischl et al. 1999) and (Fischl, Sereno et al. 1999) . I have a question about if I understood the tessellation procedure right. There are two vertexes in each voxel, but is the total number of vertex constant across brains. I believe that number of total vertex does not chang

Hi Bruce, Thanks very much for your reply. i want to convert the ".annot" files to nifti. When i used "mri_label2vol", I used this command mri_label2vol --subject fsaverage --annot $FREESURFER_HOME/subjects/fsaverage/surf/lh.ic3.annot --o test.img --hemi lh ERROR: you must specify a registr
