Fieldtrip cluster based permutation test
WebMar 1, 2024 · Hi Francois, I'm planning to do cluster-based permutation statistics with the Threshold-free cluster enhancement method which is available in fieldtrip (attached an image of the code). Is there any way I can do this in Brainstorm? I need one more help. I have to do statistical comparisons (eg cluster-based permutation) across more than 2 … WebAug 4, 2024 · To perform cluster based permutations, 14 files (1 for each subject) from condition A under were dragged under Process 2>> files A and 14 files from condition B under file B.

The objective of this tutorial is to give an introduction to the statistical analysis of EEG and MEG data (denoted as M/EEG data in the following) by means of cluster-based permutation tests. The tutorial starts with a long background section that sketches the background of permutation tests. The next sections … See more In this tutorial we will consider a between-trialsexperiment, in which we analyze the data of a single subject. For the statistical analysis for this experiment we calculate the planar TFRs. The steps we perform are as follow 1. … See more We will now show how to statistically test the difference between the TFRs in the post-stimulus (activation) and the pre-stimulus (baseline) period of the fully incongruent … See more In a between-trials experiment, we analyze the data of a single subject.
