Importing BCI200 EEG file

1

Hi,

I wonder if it is possible to import BCI200 EEG .dat into Brainstorm?

Thanks

This is not something that is possible at the moment, but we could probably add the support for this file format, as it seems to be supported by other Matlab-based toolboxes.

Can you please share an example file?
(upload it somewhere and post the download link here)

Sure, below is a link for BCI2000 data. There are 2 output files:

Thank you.
I added a first draft of the support for the BCI2000 files: IO: Support for BCI2000 .dat recordings · brainstorm-tools/brainstorm3@8cc7508 · GitHub

Please update Brainstorm and try it on various data files (new files format "EEG: BCI2000" in the drop-down menu when importing or reviewing EEG recordings).
I am not sure the reading of events is correct, as there is never more that one trigger per category.
Please check carefully the timing of the trigger, if possible in cases where you have multiple times the same trigger in the file.

Great, thanks a lot.
