apply_thresholds: Threshold additional set of matrices

Description

apply_thresholds thresholds an additional set of matrices (e.g., FA-weighted matrices for DTI tractography) based on the matrices that have been returned from create_mats. This ensures that the same connections are present in both sets of matrices.

Usage

apply_thresholds(sub.mats, group.mats, W.files, inds)

Value

List containing:

W

A 3-d array of the raw connection matrices

W.norm.sub

List of 3-d arrays of the normalized connection matrices for all given thresholds

W.norm.mean

List of lists of numeric matrices averaged for each group

Arguments

sub.mats

List (length equal to number of thresholds) of numeric arrays (3-dim) for all subjects

group.mats

List (equal to number of thresholds) of lists (equal to number of groups) of numeric matrices for group-level data

W.files

Character vector of the filenames of the files with connectivity matrices

inds

List (length equal to number of groups) of integers; each list element should be a vector of length equal to the group sizes

Details

The argument W.files accepts the same formats as A.files; see create_mats for details.

Examples

if (FALSE) {
  W.mats <- apply_thresholds(A.norm.sub, A.norm.mean, f.W, inds)
}
