I use the following findpeaks method:
peaks = findpeaks(smoothed{i}, 'MinPeakHeight',0.5,...
'MinPeakDistance',200);
the peaks matrix for this contains the y values, but I would like to have the x values. How do I get these?

If X is your array of x-values, do
[peaks,locs] = findpeaks(smoothed{i},'MinPeakHeight',0.5,'MinPeakDistance',200);
x_peaks = X(locs);
