ROIVol-class: ROIVol

In neuroim2: Data Structures for Brain Imaging Data

ROIVol

Description

A class representing a volumetric region of interest (ROI) in a brain image, defined by a set of coordinates and associated data values.

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 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 ROIVol 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.
