Hi there,

Currently, I am trying to find the periodic nature of a physical variable which has certain dynamics. To get the periodicity, I am trying to use **auto/cross-correlation** technique on **2D spatial data**. Can you please tell me whether it is possible or not in Paraview? I tried multicorrelative statistics but didn’t work.  
It would be really helpful if you suggest me any other filter which will fulfill the purpose or any link to understand **multicorrelative & Principal component analysis** filters correctly.

Thanking you.  
Best Regards,
