VertexWiseR (version 1.3.1)

TFCE_threshold: Thresholding TFCE output

Description

Threshold TFCE maps from the TFCE_vertex_analysis() output and identifies significant clusters at the desired threshold.

Usage

TFCE_threshold(TFCEoutput, p = 0.05, atlas = 1, k = 20, VWR_check = TRUE)

Value

A list object containing the cluster level results, thresholded t-stat map, and positive, negative and bidirectional cluster maps.

Arguments

TFCEoutput

An object containing the output from TFCE_vertex_analysis()

p

A numeric object specifying the p-value to threshold the results (Default is 0.05)

atlas

A numeric integer object corresponding to the atlas of interest. 1=Desikan, 2=Destrieux-148, 3=Glasser-360, 4=Schaefer-100, 5=Schaefer-200, 6=Schaefer-400. Set to 1 by default. This argument is ignored for hippocampal surfaces.

k

Cluster-forming threshold (Default is 20)

VWR_check

A boolean object specifying whether to check and validate system requirements. Default is TRUE.

Examples

model1_TFCE=readRDS(system.file('demo_data/model1_TFCE.rds', 
package = 'VertexWiseR'))

TFCEanalysis_output=TFCE_threshold(model1_TFCE, p=0.05, atlas=1,
VWR_check=FALSE)
