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
filename.
It is typically used to select files when loading a surface into Caret.
View the specification file tags.
File Header
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
-
Topo File - Defines the relationships (links) between nodes and the
nodes
that make up each tile.
-
Coord File - Defines the positions of the nodes.
Latitude Longitude Files - Contain latitude and longitude
positions
for each node in the surface.
Attribute Files
-
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
nodes
near borders that define the areas.
-
Paint File - Defines the attributes (geometry, functional, etc) for
each
node.
-
RGB Paint File - Defines an Red, Green, Blue color triplet for each
node.
-
Metric File - Defines a scalar value for each node that are mapped to
colors
using a Palette File.
-
Atlas File - Defines the probabilistic atlas assignments for each node.
-
CoCoMac - Contains Macaque connectivity information from the CoCoMac
database.
-
Surface Shape File - Defines scalar values for each node that
define
the shape of the surface such as curvature or sulcal depth.
Border Files
-
Border Color File - Defines a a lookup table of colors used by the
border
and border projection files.
-
Border File - Defines open or closed borders that are layered on the
REF
or AUX surface.
-
Border Projection File - Defines open or closed borders that are
layered
on both the REF and AUX surfaces.
-
MOMC Template File - Defines Myeloarchitectonic Templates for a border
type.
-
MOMC Template Match File - Defines the matches between each border and
each MOMC Template from the MOMC Template file.
Cell Files
-
Cell Color File - Defines a lookup table of colors for the cell and
cell
projection files.
-
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
and
AUX surfaces.
Foci Files
-
Foci Color File - Defines a lookup table of colors for the Foci and
Foci
Projection files.
-
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
and
AUX surfaces.
Coord Transform File - Specifies transformation matrices that
can
be applied to the REF surface.
Volume Comm Transform File - Specifies transformation
matrices
that are used when communicating with a volume visualization program
such
as AFNI.
Palette File - Specifies a color palette for mapping metric
data
to colors.
Topography File - Specifies information about visual
topography.
Deformation Map File - Defines a deformation from one surface
to another that can be used to deform data files without having to
rerun
the deformation.
Cuts File - Defines cuts for the surface.
Params File - A file created by SureFit that contains
parameters
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
spec
file. It is never used by Caret.
