Hi Roy,
<div><br>
</div>
<div>A warning is not an error, so that in itself shouldn’t be the issue. </div>
<div><br>
</div>
<div>What is the issue, though, is that one of the following will work:</div>
<div><br>
</div>
<div>put your my_events in the cfg, rather than the data, i.e. cfg.event = my_events, and supply this cfg to ft_databrowser(cfg,data);</div>
<div><br>
</div>
<div>put your my_events in data.cfg, rather than in data, i.e. data.cfg.event = my_events</div>
<div>
<div><br>
</div>
<div>Best wishes,</div>
<div>Jan-Mathijs</div>

<div dir="ltr">hi all,

</div>
<div>Likely I'm missing something obvious, but I'm trying to figure out how to pass an event structure read in by ft_read_event on to ft_databrowser in order to visualize events.</div>
<div><br>
</div>
<div>Reading in a Brainvision file using ft_preprocessing, followed by explicitly reading in the events and adding them to the dataset, like so:</div>
<div><br>
</div>
<div><i>%read continuous (single-trial) data</i></div>
<i>cfg=[];<br>
cfg.dataset='some_path';<br>
cfg.readbids = 'no';<br>
data=ft_preprocessing(cfg);</i>
<div><i><br>
%read the events<br>
my_events=ft_read_event(cfg.dataset,'eventformat','brainvision_vhdr','readbids','no');<br>
<br>
</i></div>
<div><i>%add to data</i></div>
<div><i>data.event=my_events;</i></div>
<div><i><br>
</i></div>
<div><i> %looks ok:</i></div>
<div><i>struct2table(data.event)<br>

</div>
<div>When I call ft_databrowser on this data strcuture, I get multiple instances of the following warning and no event markers are plotted:</div>
<div><br>
</div>
<div><i>Warning: could not determine dimord of "event" in:<br>

<div><i><br>
</i></div>
<div>Dove in a bit, and it looks like <i>getdimord </i>is called on <i>data.event</i>, which is probably not what should happen.</div>
<div><br>
</div>
<div>Any suggestions? Thanks!</div>
