ROIVec-class: ROIVec

In bbuchsbaum/neuroim2: Data Structures and IO for Neuroimaging Data with an Emphasis on Functional Magnetic Resonance Imaging (FMRI)

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 the coords 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.
