+<html><pre>
+  <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.
