 +  <a href=/​reference/​ft_channelcombination><​font color=green>​FT_CHANNELCOMBINATION</​font></​a>​ creates a cell-array with combinations of EEG/MEG
 +  channels for subsequent cross-spectral-density and coherence analysis
 + 
 +  You should specify channel combinations as a two-column cell array,
 +    cfg.channelcmb = {  '​EMG'​ '​MLF31'​
 +                        '​EMG'​ '​MLF32'​
 +                        '​EMG'​ '​MLF33'​ };
 +  to compare EMG with these three sensors, or
 +    cfg.channelcmb = { '​MEG'​ '​MEG'​ };
 +  to make all MEG combinations,​ or
 +    cfg.channelcmb = { '​EMG'​ '​MEG'​ };
 +  to make all combinations between the EMG and all MEG channels.
 + 
 +  For each column, you can specify a mixture of real channel labels
 +  and of special strings that will be replaced by the corresponding
 +  channel labels. Channels that are not present in the raw datafile
 +  are automatically removed from the channel list.
 + 
 +  When directional connectivity measures will subsequently be computed, the
 +  interpretation of each channel-combination is that the direction of the
 +  interaction is from the first column to the second column.
 + 
 +  Note that the default behaviour is to exclude symmetric pairs and
 +  auto-combinations.
