+ | <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. | ||
