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

FreeSurfer Functional Analysis Stream (FS-FAST): FS-FAST is a set of tools for performing functional MRI data analyses on the cortical surface.
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.
