[FieldTrip] ft_definetrial using data structure in workspace

[Philipp Taesler]

Hi Zita,

if you have the info about which samples belong to your trials (e.g.
extracted from some kind of marker file) you should be able to do this
by using ft_redefinetrial.

Basically you need a trial definition of the form described in the help
to ft_definetrial (a Nx3 vector with start-sample, end-sample and
zero-point offset). Then you might try something like:

cfg = [];
cfg.trl = *your Nx3 trial vector*;

segmented_data = ft_redefinetrial(cfg, imported_data);

Hope this works out for you.

All the best,
Phil
