[Freesurfer] Questions about surface coordanates

2016-08-30 Thread Dongnandi
Dear Experts, I tried to extract vertex coordinates information from 'fsaverage/surf/lh.pial' file using matlab function 'read_surf', but I found that the coordinates returned by the function are different from what I saw in tksurfer, here are the screenshots: The vertex index starts from 0 in

Dear freesurfer exports, As it is mentioned in the documentation that 'pediatric data violates the fixed head size assumption' for the current longitudinal stream. Is there any solution for the issue now? Thanks Dong ___ Freesurfer mailing list

[Freesurfer] fs6.0 mri_surf2surf failure

Dear FS experts, I'm trying to transform some files from fsaverage space to fsaverage5 space using mri_surf2surf(fs version: 6.0), however, it is weird that the results turn out to be all zeros on the fsaverage5 surface, the command line I used if : mri_surf2surf -srcsubject fsaverage -sv

[Freesurfer] mri_surf2surf failure in FS6.0

Dear Freesurfer experts, I have a binary brainmask made in volumetric space and trying to transfer it into surface space, first I use mri_vol2surf to transfer the mask into fsaverage space, then run mri_surf2surf (fs 6.0) to down sample it to fsaverage5 space. After vol2surf, some values
