Caret Data Files
Caret uses many different files, each storing a specific type of
information. View the file formats.
Specification File - The specification file groups individual
data files that define a surface. Each line in the file is a pair
of items consisting of a tag, that identifies the type of file, and a
It is typically used to select files when loading a surface into Caret.
View the specification file tags.
All data files may contain a header which may contain comment about
the file, the date the file is saved, and associations between the file
and others that define the surface.
Topology and Coordinate Files
Latitude Longitude Files - Contain latitude and longitude
for each node in the surface.
Topo File - Defines the relationships (links) between nodes and the
that make up each tile.
Coord File - Defines the positions of the nodes.
Area Color File - Defines a lookup table of colors that is used by the
Paint and Atlas files.
Areal Estimation File - Defines 4 weighted region names that contribute
to the coloring of each node. This is particularly reflected in
near borders that define the areas.
Paint File - Defines the attributes (geometry, functional, etc) for
RGB Paint File - Defines an Red, Green, Blue color triplet for each
Metric File - Defines a scalar value for each node that are mapped to
using a Palette File.
Atlas File - Defines the probabilistic atlas assignments for each node.
CoCoMac - Contains Macaque connectivity information from the CoCoMac
Surface Shape File - Defines scalar values for each node that
the shape of the surface such as curvature or sulcal depth.
Border Color File - Defines a a lookup table of colors used by the
and border projection files.
Border File - Defines open or closed borders that are layered on the
or AUX surface.
Border Projection File - Defines open or closed borders that are
on both the REF and AUX surfaces.
MOMC Template File - Defines Myeloarchitectonic Templates for a border
MOMC Template Match File - Defines the matches between each border and
each MOMC Template from the MOMC Template file.
Cell Color File - Defines a lookup table of colors for the cell and
Cell File - Defines cells that are layered on the REF or AUX surface.
Cell Projection File - Defines cells that are layered on both the REF
Coord Transform File - Specifies transformation matrices that
be applied to the REF surface.
Foci Color File - Defines a lookup table of colors for the Foci and
Foci File - Defines foci that are layered on the REF or AUX surface.
Foci Projection File - Defines foci that are layered on both the REF
Volume Comm Transform File - Specifies transformation
that are used when communicating with a volume visualization program
Palette File - Specifies a color palette for mapping metric
Topography File - Specifies information about visual
Deformation Map File - Defines a deformation from one surface
to another that can be used to deform data files without having to
Cuts File - Defines cuts for the surface.
Params File - A file created by SureFit that contains
for a surface. It is never loaded by the user, but, is specified
in the Specification File and parameters are read from it when needed.
Comment File - A text file that the user can specify in the
file. It is never used by Caret.
