http://old.fieldtriptoolbox.org/tutorial/eventrelatedstatistics WebIntroduction. 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 are more tutorial-like.
WebCluster-based tests are based on identifying clusters of meaningful effects, i.e., groups of adjacent sensors that show the same effect (see testnd for references). In order to find clusters, the algorithm needs to know which channels are neighbors. This information is refered to as the sensor connectivity (i.e., which sensors are connected).
