Hi Padma,
Freesurfer outputs volumes in conformed anatomical space (volumes in 1x1x1mm, 256x256x256).
For information on how to convert volumes back to native anatomical space, see

Best,

Subject: [Freesurfer] Original image and the mask file dimension mismatch
External Email - Use Caution
Hello Team,
I have a nifti file of dimension (256, 256, 156) but once I run the freesurfer recon-all the subregions mask "aparc.DKTatlas+aseg.mgz" has a dimension of (256,256,256) due to this I am unable to view the segmentation overlaid on
the original image in any dicom viewer.
May I know why freesurfer changes the dimension of the original image and the mask ?
Is there any solution for this?
Any help will be highly appreciated.
Thank you.
