conn_display

displays second-level analysis results

BASIC SYNTAX:

hf = conn_display(SPMfilename) SPMfilename : input file name (typically SPM.mat) containing second-level analysis results either from voxel-based analyses, surface-based analyses, or ROI-to-ROI analyses hf : output handle to results figure e.g. conn_display('/results/SPM.mat');

ADVANCED OPTIONS FOR VOXEL- AND SURFACE- LEVEL RESULTS FIGURES (applied when creating a new results figure)

hf = conn_display(SPMfilename, ncon, style) SPMfilename : input file name (typically SPM.mat) containing second-level analysis results ncon : input contrast number (if multiple contrasts are defined in 2nd-level results SPM.mat file) style : inpput voxel/cluster threshold settings (see Nieto-Castanon, 2020 for details about these methods; www.conn-toolbox.org/fmri-methods) [style=1] for default settings #1 : parametric statistics (Gaussian Random Field theory, Worsley et al. 1996) (default for volume-based results) [style=2] for default settings #2 : nonparametric statistics (permutation/randomization analyses, Bullmore et al. 1999) (default for surface-based results) [style=3] for default settings #3 : nonparametric statistics (Threshold Free Cluster Enhancement, Smith and Nichols, 2007) hf : output results explorer window handle (which can be used in advanced options described below) e.g. conn_display('/results/SPM.mat',1,3);
