Dear list,

I have received a request about .ned files that have been recorded with a
chinese EEG device from NCC MEDICAL CO. LTD.

The files are in a folder and accompanied by .nat, .egt, .txt and .prr
files. It basically goes like this
v75.egt, v75.nat, v75.ned, v75.prr, v75.txt, v76.egt...

I have tried everything. There is one article (

that mentions:
The EEG data was recorded using  24-channeld EEG machine manufactured by
NCC medical   corp., China. [...] The raw data was stored in system native
in .NED format which were subsequently converted to a .txt file for further
processing using software supplied by the NCC medical.

I tried contacting both the authors of that article and the manufacturer (

get my hands on the mentioned converter. However, they are non-responsive.

Can anybody help me out how to convert those files to load them into
MATLAB/EEGLAB? Maybe somebody has the converter available to share?
