@andins instead of using correlate try using cov
cov = data.toseries().flatten().cov().toarray()
Be careful though: for 800x800 pixels, you’re looking at (8002)2(800^2)^2 pairs of pixels. If the output comes in the form of float64 elements, then you’re looking at a correlation matrix that is easily > 3 TB in size. And this operation will be pulling that entire matrix back to your local machine for plotting.
