Hi Ruvindu,
<div><br>
</div>
<div>Your pasted code in principle looks fine. Since you don’t mention what is not working for you, I cannot provide any pointers apart from that you need to check whether the dimensions of the trial matrices are as expected (i.e. the number of rows equal to
the number of elements in the label-field, and the number of columns the same as the number of elements in the corresponding time-vector.</div>
<div><br>
</div>
<div>Best wishes,</div>
<div>Jan-Mathijs</div>

Dear FieldTrip Community,</div>

My name is Ruvindu, and I am working on converting a simultaneous EEG and NIRS dataset into FieldTrip format. It is currently in the BBCI format as I wish to use a TRENTOOL for analysis as well as I wish to analyse NIRS data in the future I am exploring this
option and convert it to FT format.</div>
