Hi @lala,
If you're interested about comparing curves, I think there might be someting using Functional Data Explorer (and specifying the curve reference ID), or the Fit Curve/Fit Nonlinear platforms (if you can find a satisfying model).
Then, you can extract parameters from the curves (for example FPCs if you're using Functional Data Explorer), and analyze which one have the closest values from the reference, using multivariate distances.
FDE also displays a "difference curve analysis" by default if you have specified your reference curve.
See some ideas in this post : Is there a way to determine how well a curve meets specification?
Hope this may help you,
