Re: [Freesurfer] Transform MNI-space segmentation into Subject-space

thank you much for your replay, but i am not sure how to use "spmregister" or "fslregister" for this purpose, becouse i want to get my MNI ROI's into the subject space, and i only have the transeformation from the subject space to the MNI space (instead of the inverse- from MNI space to the subject

You need to create a registration between your subject and your MNI space. Try using spmregister or fslregister (but not bbregister). But there is a bigger problem in that surface-sampling of ROIs in MNI space tends not to do very well, but I'll leave that up to you to evaluate On 09/29/2014

Hello I have a segmentation which made on MNI space, is it possible to do the inverse transform to the segmentation from MNI space to each subject space? does the size of the MNI segmentation (218*182*182) should be a problam? I was traing : mri_vol2surf MNI_Segmentation.nii --hemi lh --regheade
