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
