There are several metrics that one can use to test a morphometry-related hypothesis such as gray matter volume, white matter volume, cortical thickness, or cortical curvature. This talk will describe two techniques for analyzing brain morphometry: voxel-based morphometry (VBM) and surface-based analysis (SBA).
List of services:
This kind of data is analyzed using SMP (SPM12), CAT 12 or Freesurfer (ROI analysis and vertex wise analysis (by FSGD or QDEC)). These analyses are included Voxel-based morphometry, Deformation-based morphometry, Region-based morphometry and Surface-based morphometry.

One of the important steps in preprocessing in Freesurfer that we do is quality control and manually change certain files created during the recon-all processing stream and then regenerate the surfaces.
