FreeSurfer Surface to Volume Projection

Library: FreeSurfer | Docker Image: freesurfer/freesurfer

Function

Projects surface-based data back to volumetric space using registration and template volume.

Modality: FreeSurfer surface overlay file plus template volume and registration.

Typical Use: Converting surface-based results back to volume space for reporting.

Key Parameters

--surfval (surface data), --reg (registration), --template (output grid template), --hemi (hemisphere), --o (output volume)

Key Points

Inverse of mri_vol2surf. Template defines output grid dimensions.
