%% The correct pipeline order for combining planar MEG channels
%
%% # Description
%
% This script demonstrates the pipeline sequence you should follow when you use **[ft_combineplanar](https://github.com/fieldtrip/fieldtrip/blob/release/ft_combineplanar.m)** in your induced Time-Frequency and Event-Related Fields analysis. This script is specific for MEG datasets that have axial/magnetometer sensors (CTF, Elekta) and you're interested to compute a synthetic planar representation.
%
%% # Example dataset
%
% It requires CTF275 gradiometer description data, which is available [here](ftp://ftp.fieldtriptoolbox.org/pub/fieldtrip/example/megrealign/ctf275.mat)

% The following code creates a single dipole that projects brain activity on posterior sensors. We simulate an alpha component (10Hz) whose power decreases after a hypothetical visual stimulus delivery. The signal itself is not very important (you can design your own).
