I am not certain what you want to do.
If you want to get the peaks and their indices, request those outputs:
[pks,locs] = findpeaks(pure_brain(:,2)); % Get Peaks (‘pks’) and Peak Indices (‘locs’)
I have no idea what is in your data file, however if you want to plot them and indicate them, try this:
x = 1:size(pure_brain,1);
figure
plot(x, pure_brain(:,2))
hold on
plot(x(locs), pure_brain(locs,2), '^r')
hold off
grid
.
