ROIVec
Description
A class representing a vector-valued volumetric region of interest (ROI) in a brain image.
Slots
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
matrix
containing the data values associated with each voxel in the ROI. Each row corresponds to a unique vector value, and the number of rows should match the number of rows in thecoords
matrix.
Validity
An object of class ROIVec
is considered valid if:
- The coords
slot is a matrix with 3 columns.
- The .Data
slot is a matrix.
- The number of rows in the .Data
matrix is equal to the number of rows in the coords
matrix.
