[FieldTrip] Defining trials

[Schoffelen, J.M. (Jan Mathijs)]

Hi Mubeen,

You’d need to write your own ’trialfun’ if you want to achieve what you want. See: https://www.fieldtriptoolbox.org/example/making_your_own_trialfun_for_conditional_trial_definition/
to get started.

Good luck,

Jan-Mathijs

Hi all,

Following up on this. Could someone help me with this code please.

cfg = ft_define trial

I have event labels on my file 'ep.sw' and 'end' defining segments of interest

How can I create trials around only segments between 'Ep.sw' and 'end'. I dont know where to define the end segment for each trial. In the edf file label its named 'end'.

Regards,
Mubeen

Subject: Defining trials

Hi all,

Can I get help with a code to allow my edf files each with a number of segments labelled 'ep.sw' at the start and 'end' at end of segment of interest (ranging between 2-10 seconds).

The stim and response based entries in code is abit confusing for me as a beginner and I would just like to define trials based on start and end markers I have mannually marked on segments of a continuous EEG.

All help will be much appreciated.

Regards,
Mubeen
