My project is to record raw brain signals using the emotive epoc 14 channels. what i wanted to do is show a participant an image for a particular time(such as 1 min) and record his brain signal of that time to a separate csv file of that particular time. I want to repeat the process of a different image. after 1 min, the second picture will appear on the screen and the brain signal of the second photo will save in a different csv file for that time. Finally i want to repeat the process 10 times with 10 photos and will generate 10 csv file of raw EEG signals.
As i am new to the node-red and emotive epoc. it would be great full if someone guides me how to creat the flow or any tuttorial how to do it.
