A .bdf file is not loading properly into EEGLAB.
I have trying to recreate the procedures of an EEGLAB experiment. Here, .bdf files were imported using the BIOSIG interface producing a result like so:
However, when I upload these files using this interface I get this result:
Note that there is some differences here (like the epochs), but primary concern is that not all the channel data appears to be there.
Specific channel frequency data will not be visible until you run a high-pass filter to remove high frequency noise - doing so will reveal the signal from each specific channel.
