2013-05-06: This is the old Camino website. The latest versions of the code and related information are at http://cmic.cs.ucl.ac.uk/camino

Camino is a free, open-source, object-oriented software package for analysis and reconstruction of Diffusion MRI data, tractography and connectivity mapping.

Key Features

  • Reconstruction techniques including:
    • Fitting the Diffusion Tensor to diffusion-weighted MRI data.
    • Standard scalar measures, such as FA and Tr(D).
    • Fitting 2 and 3-tensor models.
    • Advanced reconstruction algorithms including RESTORE, q-ball, and maximum-entropy spherical deconvolution (including PAS-MRI).
    • ActiveAx axon diameter and density mapping
    • White matter compartment model fitting
  • Data synthesis
    • Generate synthetic data from standard diffusion tensors.
    • Generate synthetic data from full diffusion tensor images.
    • Generate synthetic data from other models of diffusion within restricting media.
    • Generate synthetic data by Monte-Carlo simulation of diffusion within restricting geometries.
  • Deterministic and probabilistic tractography (PICo), including:
    • Tractography and connectivity mapping with single and multiple tensor models.
    • Waypoints, exclusion regions, and multiple-ROI processing.
    • Output connection probability maps, or save streamlines in raw binary, VTK, or OOGL (GeomView) format.
    • PAS-PICo and Q-Ball PICo
  • DT image warping
    • Preservation of principal directions (PPD)
    • Finite strain approximation
  • Useful sets of gradient directions for diffusion MRI acquisition protocols.
    • Electrostatic point sets
    • Ordered point sets for improved realignment and partial acquisition.
  • Full documentation via
    • Unix man pages
    • A variety of tutorials illustrating common tasks
    • Standard javadoc for the source code.
