ABOUT THE NE ASCII DATA FORMAT (July 2012): 

% NE ASCII files contain one line per time sample. Each line contains % first the EEG data (8 or 20 channels, depending on the device, with % units in nV), followed by three acceleration channels (aX,aY,aZ % in mm/s^2- millimeters per second squared), an *optional* external % input channel, a trigger flag (int32) and, finally, % a timestamp in Unix time (ms from Jan 1 1970): % % Ch1(nV) ... Ch8or20(nV) aX(mg) aY(mg) aZ(mg) AddSensor Flags(uint32) TimeStamp (ms) % % Therefore Enobio8/StarStim will have a minimum of 8+2 (10) columns, or 8+3=11 if no % accelerometer or >= 8+4 (with accelerometer). In summary: % % Enobio8/20 % 10 Columns: no AddSensor, no accelerometer data: % 11 Comumns: no accelerometer, but there is AddSensor % 13 Columns: there is accelerometer, but no Addsensor % 14 Comumns: there is accelerometer, AddSensor. % % Enobio 20 will have >= 22 and >=24 columns if acc. data present: % 22 Columns: no AddSensor, no accelerometer % 23 Comumns: no accelerometer, but there is AddSensor % 25 Columns: there is accelerometer, no AddSensor % 26 Comumns: there is accelerometer, AddSensor. % % Enobio 32 will have >=34 adn >=36 if acc data is present % 34 Columns: no AddSensor, no accelerometer % 35 Comumns: no accelerometer, but there is AddSensor % 37 Columns: there is accelerometer, no AddSensor % 38 Comumns: there is accelerometer, AddSensor.
