Our tools

Structural MRI

FreeSurfer provides a full processing stream for structural MRI data, including:

  • Skull stripping, B1 bias field correction, and gray-white matter segmentation
  • Reconstruction of cortical surface models (gray-white boundary surface and pial surface)
  • Labeling of regions on the cortical surface, as well as subcortical brain structures
  • Nonlinear registration of the cortical surface of an individual with a stereotaxic atlas
  • Statistical analysis of group morphometry differences

Functional MRI

Diffusion MRI

  • TRActs Constrained by UnderLying Anatomy (TRACULA): TRACULA is a tool for automated probabilistic tractography with anatomical priors. It reconstructs a set of major white-matter pathways by incorporating prior information on the structural segmentation labels that each pathway goes through or next to, at every point long the pathway's trajectory. It includes a specialized stream for processing longitudinal diffusion MRI data.


  • Registration tools: FreeSurfer offers a range of tools for both within-subject and across-subject registration.
