Hi,
So I'm really new at working with EEG data and I am having trouble finding the peaks of data I imported from a csv file. This is the error I keep getting:
I can't find where the 'non-increasing' part of the timestamp is, and I don't know how to fix the problem. Can someone please help me with this?
I've attached a zip folder with the csv file I used and the Matlab code I tried to use.

You reversed the inputs. It's findpeaks(y, x), not findpeaks(x, y):
[peakValues, indexesOfPeaks] = findpeaks(AF3, timestamp);
