What can I do with it?

You can make EEG csv file to heatmap file. 1 2 Raw data go through Butterworth highpass filter, cut-off as 30Hz, sampling frequency as 1000, order as 4, then adjust the data, and absolte it. Absolted data go through Butterworth lowpass filter, cut-off as 15Hz, sampling frequency as 1000, order as 4, and normalize it. Finally, those data become a heatmap.

How I preprocess the csv file?

First, you have to make csv data as; (In this example, a, b, etc is data.)

ch1 ch2 ch3 ch4 ...
a   b   c   d   ...
e   f   g   h   ...
.   .   .   .
.   .   .   .
.   .   .   .

If your csv file has no header, you may have to revise this python file(or csv file).

How I use it?

ⓐ Write file name at var file_name.

ⓑ You can manipulate the heatmap window size. Set var nWindowSize.

ⓒ If you succeeded runnung this file, you can get heatmap csv data file, and heatmap plot png.
