 ☛ Construct a vector of timestamps containing the time, starting with 0, of each of the 8448 samples in this data. This requires knowing the sampling rate of the Emotiv; consult the manual or the file header to find this out. Then, replot the data using this time vector. ☛ Construct a vector of timestamps containing the time, starting with 0, of each of the 8448 samples in this data.

 +==== Optional: streaming Emotiv data ====

 +If you want to access Emotiv data in (near) real-time, rather than loading a previously saved file, I recommend using the FieldTrip toolbox. Use Git, as above, to clone the current FieldTrip repository. Then, in MATLAB, add it to your path as follows:
 +
 +<​code>​
 +cd('​C:​\Users\mvdm\Documents\GitHub\fieldtrip'​);​
 +ft_defaults;​
 +</​code>​
 +
 +Make sure your Emotiv headset is on and you have the Bluetooth receiver'​s light flickering. Then, from a command prompt, launch the following two executables:​ `buffer.exe` (in \GitHub\fieldtrip\realtime\bin\win32) and `./​emotiv2ft.exe emotiv-config.txt`. If that looks like it's working (you should get some status updates showing up in the command prompt), do this in MATLAB:
 +
 +<​code>​
 +ft_realtime_plot([])
 +</​code>​
