<b>Subject:</b> Re: [FieldTrip] TRENTOOL bad channel combinations</font>
<div> </div>
</div>
<div>Hello Tyler,<br>
<br>
TRENTOOL does not support the exclusion of channels like FieldTrip does (e.g. {'all', '-MLx', '-EOG'}), you have to explicitly specify channels OR combinations of channels for analysis in the cfg structure passed to TEprepare:<br>
<br>
% cfg.sgncmb = list of channelpairs cell array (Nx(source, target))<br>
% or<br>
% cfg.channel = list of channels cell array - testing will be done all-by-all<br>
<br>
If you provide a list of channel combinations in cfg.sgncmb, TRENTOOL will analyze these combinations only; if you provide a list of channels in cfg.channel, TEprepare will build all possible channel combinations from the list and TRENTOOL will analyze these
combinations. (Also, channel names have to match the channel labels in data.label.)<br>
<br>
So, a way to exclude bad channel combinations would be to provide a list of all channels that should be included in the analysis in cfg.channel and let TEprepare build the channel combinations from that.
<br>
<br>
I hope this answers your question. Please let me know if you encounter any more problems.<br>
<br>
Best, <br>
Patricia<br>
<br>
