Nihon Kohden: EEG-1200A V01.00

[ftadel]

Hello,

I adapted nk2edf.cpp from EDFBrowser in Matlab, which I guess was initially coming from the biosig implementation (or did it go the other way around?)
Biosig: https://github.com/donnchadh/biosig/blob/master/biosig4c%2B%2B/biosig.c#L597
EDFBrowser: https://github.com/Teuniz/EDFbrowser/blob/master/nk2edf.cpp#L1419
Brainstorm: https://github.com/brainstorm-tools/brainstorm3/blob/master/toolbox/io/in_fopen_nk.m#L316

It works great and it allows Brainstorm users to read directly Nihon Koden .EEG files, thanks to all of you.

However, it suffers from the same limitations: the new systems are not supported...
See the related EDFBrowser issue:
https://github.com/Teuniz/EDFbrowser/issues/28

Do you have any information about the new NK file format?
Do you know where the first version of this C code came from? Would it be possible to get updated specifications in the same way?

Thanks,
Francois
