[Eeglablist] file not properly imported from bdf files with EEGlab multiple versions #506

[Delorme, Arnaud]

We have added that option to import events in different modes (and others) to the BIOSIG import GUI of EEGLAB and it will be available in the next version of EEGLAB.

Best wishes,

Arno

By default "Mode=4" is used for the translation. It seems that your data requires a different decoding mode. Most likely some of the other decoding modes is more suitable for your data.
