During the workshop I tried replicating what we learned on my own data but a problem rose with the reading of events and it could not be solved in the context of the workshop. </div><div><br></div><div>To summarize, I work with EGI data (format .mff). The stimuli are 480 short videos with characters saying sentences and trigger events are coded as follow: </div><div>- a first trigger at the onset with a unique code corresponding to the ID of the sentence (40 different stim) </div><div>- a second trigger during the stimulus coding for condition (2 different stim)</div><div>- a third trigger at the end of the video coding for the ID of the character (6 different stim)</div><div>- a fourth trigger after the video coding for the participant's answer on the keyboard to a question (4 different stim)</div><div><br></div><div>When I import the data I use the following script: </div><div><a href="https://gist.github.com/rtheze/31bef97aa0f4fff1b1506e1611746012" target="_blank">https://gist.github.com/rtheze/31bef97aa0f4fff1b1506e1611746012</a><br></div><div><br></div><div>I can't publicly share the data, but if someone is wiling to run some test I can send a dataset in a private message. </div><div><br></div><div>The problem is when I print events, for instance 'D206' or 'D208' which correspond to condition trigger I respectively have 200 and 203 events found, while I should have 240 of each. </div><div><br></div><div>I know for certain that the data is ok because I work with it in matlab (fieldtrip) and the number of events is as expected. The only option I see is the that the mne function does not read properly the .mff data but before opening an issue I prefer to ask for advice. </div><div><br></div><div>In advance, thank you for your help</div><div>Best, </div><div>Raphaël Thézé</div></div>
