Hi Holly,

You should first create this function, by copying and pasting from the example (essentially just take the second block of code on the page you are working from).
Then, you may need to adjust a bit of the code for your own purpose (most likely the name of the emg-channel.

Good luck,

Hi there,

I am trying to use the muscle activity from an EMG channel to use as a trial definition and have found the tutorial on it but it doesn’t seem to recognise the term ‘trialfun_emgdetect’ – I’ve tried with the most recent version of fieldtrip and it’s still not working. This is the error I’m getting:

Undefined function 'func2str' for input arguments of type 'double'.

Error in ft_definetrial (line 158)
    error('the specified trialfun ''%s'' was not found', func2str(cfg.trialfun));
