[FieldTrip] define events for ft_definetrial

[jan-mathijs schoffelen]

Dear Beth,

It could be that your dataset is corrupt.

This is namely a low level reading error. It then percolates to the  
next step, where

which is most likely caused by FieldTrip not having been successful in  
creating an event structure.

Does this pertain to this particular dataset?

Best

PS: please update to a more recent version of FieldTrip: the content  
of the line number in which the errer occurs does not coincide with my  
version
