Hi
with cyton board when I saved the recording with CSV and I wanted to find the calculation for the cells in a CSV file, didn't give me any answer. what is my error.
with thanks
I have a cyton board and I want to print the EEG signals with a printer any method to do this task? I search a lot but I don't find the correct answer.
My regards

There is a separate column in the csv for each Cyton data channel. Each row represents one set of samples. Samples come 250 times per second, or every 4 milliseconds.
There is a form of data processing called "digital signal processing", which can do various operations on such data samples. One of the most useful operations is to 'filter' the data stream into some range of frequencies. These frequency bands represent different brainwave frequencies. Such as delta, theta, alpha, beta, gamma.

One 'simple' way you might print the signals, is to just take screenshots of whatever OpenBCI_GUI windows you find interesting. There are also many free programs online that can read and plot csv files.

As one example, the program EEGLAB can perform various signal processing operations. But it requires that you have MATLAB installed.

Another free plotting package is EDFBrowser,

Note that Cyton data needs to be first filtered to remove the DC offset (frequencies below .5 Hz).
