[Eeglablist] exporting to BrainVision format

[K Jeffrey Eriksen]

I am trying to get some Neuroscan.cnt EEG files into OpenViBE, This what I have tried:


  1.  File -> Import data -> Using EEGlab functions and plugins -> from Neuroscan .CNT file
  2.  File -> export -> write Brain Vis. exchange format file

These steps work OK, creating .DAT, .VHDR, and .VMRK files. The problem occurs when I use the [BrainVision Format file reader] box (function) in OpenViBE. It complains that the EEG is not "multiplexed" and stops. This most likely means it has simply been transposed from (icolumn, irow) to (irow, icolumn) or visa versa, depending on conventions.

I see that the EEGlab BV export process relies on the "bva-io" code. I could perhaps solve my problem by creating a local version of bva-io (my_bva_io perhaps) that transposes the data. But I would probably need advice from someone in order to do it right.

One further thought is that perhaps the .CNT file is not in the usual order and this gets passed to the BV format file.
