NeuroSpace Class

Represents the geometry of a brain image.

Slots

dim

An integer vector representing the grid dimensions of the image.

origin

A numeric vector representing the coordinates of the spatial origin.

spacing

A numeric vector representing the dimensions (in mm) of the grid units (voxels).

axes

A named AxisSet object representing the set of spatial axes in the untransformed native grid space.

trans

A matrix representing an affine transformation that converts grid coordinates to real-world coordinates.

inverse

A matrix representing an inverse transformation that converts real-world coordinates to grid coordinates.

Validity

The NeuroSpace object is considered valid if: - The length of the @dim slot is equal to the lengths of the @spacing, @origin, and number of axes in the @axes slots. - The @dim slot contains non-negative values.

Usage

The NeuroSpace class is used to store and manipulate the geometric properties of a brain image.

Examples

# Create a NeuroSpace object
space <- NeuroSpace(dim=as.integer(c(64, 64, 64)), origin=c(0, 0, 0), spacing=c(1, 1, 1))
