OpenBCI x Emotibit xdf file import error #826

Open Julluke opened 1 week ago

Julluke commented 1 week ago

Hi EEGLAB Community!

I have a measurement system consisting of Emotibit and the OpenBCI Ultracortex Mark IV. I have saved all data streams from both devices via LSL Stream in an xdf file. Now I have problems with the EEGLAB plugin “Mobilab”. When I try to import the xdf file, the widget opens, but it is empty (file attached). I also cannot run the "Load MoBi folder" command. I'm using Matlab 2024 and the latest verison of eeglab and mobilab plugin, since i've read some posts about errors using non compatible versions, but didnt quite understand what i should change. Has anyone here tried a similar setup or had similar problems with the plugin? Since i'm not dependent on using eeglab for this purpose, is there any other way of using Emotibit data with other data in an xdf file?

Any suggestion would be helpful.

Thank you very much in advance :)

Jule

Yes this is a known issue. Can you try the EEGLAB xdf plugin?

Thanks for the quick reply!

I can import the data via "Import File -> xdf" of the EEGLAB GUI. But then only the 16 EEG channels can be seen. I also checked the xdf file in Matlab with "load_xdf". There can all data streams be plotted, but the 16 Channels of the eeg are not separate. And especially this would be the major benefit of EEGLAB, as i suggest.

Thank you very much in advance for any help :)

We will try to remedy that problem, do you have a file to share?

Yes of course, here is the file i'm using. Please consider, this was only for testing the setup and no significant data is expected. This zip file should work: sub-P001_ses-S001_task-Default_run-001_eeg.zip

Thanks a lot for your effort :)

OK, thanks. We should have something next week.
