<br>
it is a bit confusing that you call the variable returned from
ft_definetrial 'data1', because actually it is only a
cfg-structure without data. No matter how you call that variable
though, it should work if you use this:<br>
<br>
<i> data1.artfctdef.reject = 'complete'; </i>
<div><i> data1.artfctdef.jump.artifact = artifact_jump;</i></div>
<div><i> data1.artfctdef.muscle.artifact =
artifact_muscle;</i></div>
<div><i> data_no_artifacts = ft_rejectartifact(data1)</i></div>
<br>
Note that you need to call ft_preprocessing in order to obtain
data, in your case:<br>
<br>
<i>data = ft_preprocessing(data_no_artifacts);</i><br>
or <br>
<i>data = ft_preprocessing(data1);</i><br>
<br>
ft_definetrial is a function which just returns at what samples
your trials are supposed to start. ft_preprocessing is then using
this information to extract the trials out of your datafile. You
can artifact rejection either before you segmented the data into
trials, as done here, or afterwards, i.e. after having called
ft_preprocessing.<br>

<div>Thank you for your suggestion. But unfortunately this doesn't
work. If I do your way I get: Error using ft_rejectartifact
(line 233)</div>
<div>no trials were selected, cannot perform
artifact detection/rejection.</div>

</div>
<div>So I am still not sure what might be the problem...</div>
