WebJul 1, 2011 · Hello, I'm new to field trip and I have two short questions regarding time-frequency analysis: I'm using field trip for averaging time frequency plots of 11 subjects obtained by BESA 5.3. For every subject I have two conditions, and I want to calculate (using statistical clustering) the difference bettween the two conditions. In this tutorial we will analyze the power spectra for two different EEGdatasets. The first dataset is recorded in a language task,the second dataset is recorded in a resting-state experiment.Before starting with this tutorial, please read through the linked descriptionsof the two datasets.
