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. http://old.fieldtriptoolbox.org/reference/ft_connectivity_wpli
