FreeSurfer is a set of tools for analysis and visualization of structural and functional brain imaging data. FreeSurfer also refers to the structural imaging stream within the FreeSurfer suite.
FreeSurfer provides many anatomical analysis tools, including: representation of the cortical surface between white and gray matter, representation of the pial surface, segmentation of white matter from the rest of the brain, skull stripping, B1 bias field correction, nonlinear registration of the cortical surface of an individual with an sterotaxic atlas, labeling of regions of the cortical surface, statistical analysis of group morphometry differences, and labeling of subcortical brain structures.
