In bbuchsbaum/neuroim2: Data Structures for Brain Imaging Data

Extract time series from specific voxel coordinates and return as ROI object

Description

Extracts time series data from a NeuroVec object at specified voxel coordinates and returns it as an ROI object.

Usage

series_roi(x, i, ...)

Arguments

x	The NeuroVec object
i	Numeric index for the first dimension
...	Additional arguments

Value

A ROIVec object containing the time series data for the specified coordinates.

Examples

# Create a simple 4D neuroimaging vector
space <- NeuroSpace(c(10,10,10,20), c(1,1,1))
vec <- NeuroVec(array(rnorm(10*10*10*20), c(10,10,10,20)), space)

# Extract time series for first 100 voxels as ROI
roi1 <- series_roi(vec, 1:100)

# Extract time series using 3D coordinates
coords <- matrix(c(1,1,1, 2,2,2, 3,3,3), ncol=3, byrow=TRUE)
roi2 <- series_roi(vec, coords)
