SurfaceGeometryMetaInfo Class

The `SurfaceGeometryMetaInfo` class encapsulates meta information for brain surface geometry. It stores details about the file locations, surface properties, and spatial characteristics.

Value

An object of class SurfaceGeometryMetaInfo.

Details

This class is crucial for maintaining metadata about brain surface geometries. It provides a structured way to store information about file locations, surface properties, and spatial characteristics, which is essential for proper handling and processing of brain surface data in neuroimaging analyses.

Slots

header_file

A character string specifying the name of the file containing meta information.

data_file

A character string specifying the name of the file containing the actual surface data.

file_descriptor

An object of class `FileFormat` describing the image file format.

vertices

An integer indicating the number of surface vertices.

faces

An integer indicating the number of faces in the surface mesh.

embed_dimension

An integer specifying the dimensionality of the embedding (typically 3 for 3D surfaces).

label

A character string indicating the type of surface (e.g., "white", "pial", "inflated", "flat", "spherical").

hemi

A character string indicating the hemisphere ("lh" for left, "rh" for right, or "unknown").

                 header_file = "surface_meta.txt",
                 data_file = "surface_data.gii",
                 file_descriptor = new("FileFormat"),
                 vertices = 40000L,
                 faces = 79998L,
                 embed_dimension = 3L,
                 label = "white",
                 hemi = "lh")
