Welcome to the FreeSurferWiki. The FreeSurferWiki is the central documentation and download source for FreeSurfer, a software application developed at the Martinos Center for Biomedical Imaging by the Laboratory for Computational Neuroimaging.

FreeSurfer is a set of tools for analysis and visualization of structural, functional, and diffusion MRI brain imaging data. FreeSurfer contains a fully automatic structural imaging stream for processing cross sectional and longitudinal data.

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 a stereotaxic atlas, labeling of regions of the cortical surface, statistical analysis of group morphometry differences, and labeling of subcortical brain structures and much more ...
