Dear all..
I have succeed to record all signals from Neurosky (raw data, alpha beta, etc) using Openvibe into csv file.
However, when I open the csv file it seems that all signals, other than the raw electrode signal, are being written 512 times repeatedly the same values.
I guess it is because the sampling rate of Neurosky is 512, while the eSense signal (alpha/beta/attention/meditation/etc) are being update per second.
my question is, How to record Neurosky eSense signals without repeating @ 512 times ?
Or how to record values per second (despite the sampling rate is fixed 512)?
best regards

Re: How to record Neurosky signals without repeating @ 512 t
Just guessing here, but would you be able to process the sample with the Signal Decimation box? I haven't tested it, but by description it looks like it does downsampling.

Dear jlindgren
thanks a lot
I will try to use the Signal Decimation box, with decimation factor = 512 (to reduce sampling rate 512 into per second)
