[Eeglablist] Export to bdf file: unwanted changes in event type, number events and number of channels

[Hannes Almgren]

Dear all,


I would like to make changes to a bdf file (EEG dataset) using EEGlab. I load the file using 'file > import data > using EEGlab functions and plugins > from biosemi bdf file (BIOSIG toolbox)'. When I export the data in bdf format using 'File > Export > Data to EDF/BDF/GDF file', I lose 25 of 75 events and 1 of 111 channels (event types also change).  This also happens when I do not make any changes to the bdf file (import and export same data).


Does anybody have an idea what the problem could be and how to solve it? I already searched on the internet for possible solutions, but nothing worked.


I am using EEGlab v14.1.1 (Ubuntu version  16.04).


Kind regards,


Hannes
