<div>Hello Tarik,</div>
<div><br /></div>
<div>Thanks a lot for the reply and the suggestions. </div>
<div><br /></div>
<div>To circumvent any of the potential problems that may arise using my data, I did the analyses using the tutorial data that was used in the youtube tutorial (https://www.youtube.com/watch?v=Sup2SaJyFQE).</div>
<div><br /></div>
<div><i>1. From what it looks like in the images you showed, you may not be</i></div>
<div><i>filtering the data properly as per BCI import functions.</i></div>
<div><i>Take a closer look through the bcilab documentation on that.</i></div>
<div><br /></div>
<div>I tried multiple versions:</div>
<div>a) Used the Raw tutorial data as is.</div>
<div>b) Filtered the tutorial data (1Hz lower boundary)</div>
<div><br /></div>
<div>With every dataset, I get the same error when I 'inspect data' on bcilab.</div>
<div><br /></div>
<div>Here is the error message when the display window pops up:</div>
<div><br /></div>
<div>io_loadset(): loading /Users/nilu/Desktop/BCILAB-devel/userdata/tutorial/flanker_task/12-08-002_ERN.eeg...</div>
<div> using montage resources:/caps/Standard-10-5-Cap385.cap.</div>
<div>Converting all numeric event types to strings.</div>
<div>on_resize failed.</div>
<div>Current plot held</div>
<div><br /></div>

<div><i>2. You should not be experiencing data loss. This may be due to the very</i></div>
<div><i>long length of your total data, or to "epoching" settings in the bcilab</i></div>
<div><i>import function.</i></div>
<div><br /></div>
<div>Th tutorial data (12-08-002_ERN.vhdr) is not long (753.5 seconds, 809 events), so this should not be an issue anymore. Instead of data loss here, I see data overlap.</div>
<div><br /></div>
<div><i>3. In the future, and for this email, you probably want to also CC</i></div>
<div><i>Dr.Kothe, the developer of BCILAB. You may also want to check that you</i></div>
<div><i>original data are okay (via a non-bcilab path), and that you have the most</i></div>
<div><i>recent versiosn of bcilab/eeglab.</i></div>
<div><br /></div>
<div>The original data should be okay now that I am using the tutorial dataset that comes along with BCILAB. Also, the data looks fine when I open the data with EEGLAB. The X and Y axes are what is to be expected.</div>

<div><i>4. One alternative you could consider is to properly load up the files</i></div>
<div><i>within eeglab, save them as .set files, confirm that they are OK, and that</i></div>
<div><i>they have all the data, and then from there attempt loading them into</i></div>
<div><i>BCILAB.</i></div>
<div><br /></div>
<div>I tried this but the problem still persists.</div>
<div><br /></div>
<div><i>5. If you lack of events is only due to the data loss, once you resolve</i></div>
<div><i>proper import, you should be fine. If you need to add event markers, you</i></div>
<div><i>should be able to do that via eeglab or bcilab functions.</i></div>
<div><br /></div>
<div>Yes, the lack of events is due to data loss in my data.</div>
<div><br /></div>
<div><i>6. When you have a solution to your queries, please share them with the</i></div>
<div><i>list so that other users can benefit from your experiences.</i></div>
<div><br /></div>
<div>Sure, will be glad to.</div>
