External Email - Use Caution
Dear Freesurfer developers,We have a volume that assigns unique numerical labels to each of the ROIs it contains, in NIFTI format. I want to register it to MNI152 (1mm) space, so that I can map it on my subjects and use mris_anatomical_stats.I have tried the following command: 1. tkregisterfv --mov MDROI.nii --s MNI_1mm --regheader --reg registrationMD/MDROI.lta
to get : "LTA input is not RAS to RAS...converting...". Then I run: 2. mri_vol2surf --src MDROI.nii --src_type nii --out registrationMD/surf.MDROI.mgh --reg registrationMD/MDROI.lta --hemi lh --surf white --projdist-max 0 1 0.1 3. mri_vol2surf --src MDROI.nii --src_type nii --out registrationMD/surf.MDROI_rh.mgh --reg registrationMD/MDROI.lta --hemi rh --surf white --projdist-max 0 1 0.1The 2 commands above demand the --hemi argument, but I wasn't sure what to put, as the ROIs are mixed and are in both hemispheres. Thus I run the command once for the left and once for the right hemisphere, creating different .mgh files.Last, I continued with:
4. mri_vol2label --i registrationMD/surf.MDROI.mgh --id 1 --l lab.MDROI_lh.label --surf MNI_1mm l which failed, as I get "ERROR: found no voxels matching id 1" Could you please tell me, if the commands make sense, and if I should change something?
Thank you so much for your help! Best regards,Eleni
