ICAspat: ICAspat

In AnalyzeFMRI: Functions for Analysis of fMRI Datasets Stored in the ANALYZE or NIFTI Format

Description

This function performs a spatial ICA

Usage

ICAspat(X,n.comp,alg.typ="parallel",centering=TRUE,hp.filter=TRUE)

Arguments

X	a matrix of size tm x vm which contains the functionnal images
n.comp	number of maximally independent components to extract
alg.typ	if 'alg.typ == "parallel"' the components are extracted simultaneously (the default). if 'alg.typ == "deflation"' the components are extracted one at a time.
centering	Logical. Should we center the data first. Centering will be performed by firstly removing the column mean.
hp.filter	Logical. Should we perform high-pass filtering on the data

Value

A list containing

time.series	estimated mixing matrix of size tm x n.comp
spatial.components	estimated source matrix of size n.comp x vm
