What do you mean by "the average space of the subjects"?

External Email - Use Caution
Dear Freesurfer experts,
I am aware that these are busy times. Please still allow me to repost my FreeSurfer problem:
I created manual masks on the Freesurfer input 001.mgz for several subjects. I would like to to transform all these individual masks to the average space of the subjects.
For this, I first ran mri_vol2vol:
mri_vol2vol --talres 1 --interp nearest --mov SW1-2039/BGmaskbin.nii.gz --s SW1-2039/001.nii --targ multiplems_average/mri/T1.mgz --regheader --o BG2039mask_avesp.mgz
The output from that was then used to run mri_robust register
mri_robust_register --mov BGmask2039_avesp.mgz --dst multiplems_average/mri/T1.mgz --lta BG_2039_reg.lta --mapmov BG_2039_reg.mgz --iscale --satit
But this does not seem to do the job.
How can I transform and register a mask to the average space?
Many thanks for your help!
Best regards, Ben

How I can I correct this? Do I need to register the native and MNI template first? Thanks! /Ben Am Fr., 6. März 2020 um 17:59 Uhr schrieb Douglas N.

If you want to transfer the orig.mgz, you can do it with mri_vol2vol --tal --talres 1 --interp nearest --mov orig.mgz --s subject --o example.mni305.mgz On 2/20/2020 3:53 PM, Benjamin Ineichen wrote:External Email - Use Caution Dear Freesurfer experts, In order to transform a segmentation mask (example.mgz) from native so standard MNI space I ran: mri_vol2vol --talres 1 --interp nearest --mov example.mgz --s 001.mgz --targ $FREESURFER_HOME/subjects/fsaverage/mri/orig.mgz --regheader --o example.mni305.mgz the output example.mni305.mgz did somehow transform to a different space as you can see in Screenshot orig where the native mask is white and the transformed mask is red. However, the masks seems to be in a completely different brain region in the native MNI space (Screenshot MNI). But the point of transforming my segmentation mask is that the segmented mask should be in the same brain region but just transformed to the standard space. How can I correct this?
