ROIVolWindow

A class representing a spatially windowed volumetric region of interest (ROI) in a brain image, derived from a larger parent ROI.

Slots

parent_index

An integer representing the 1D index of the center voxel in the parent space.

center_index

An integer representing the location in the coordinate matrix of the center voxel in the window.

coords

A matrix containing the 3D coordinates of the voxels within the ROI. Each row represents a voxel coordinate as (x, y, z).

.Data

A numeric vector containing the data values associated with each voxel in the ROI. The length of this vector should match the number of rows in the coords matrix.

Validity

An object of class ROIVolWindow is considered valid if: - The coords slot is a matrix with 3 columns. - The .Data slot is a numeric vector. - The length of the .Data vector is equal to the number of rows in the coords matrix.
