How to calculate Average Wavelet Coherence (AWC) and Percent area of significant coherence (PASC)?

Hi all, I have done the wavelet coherence plots using "Crosswavelet and wavelet coherence software were provided by A. Grinsted. I would like to do a quantitative analysis of the wavelets and calculate the average wavelet coherence (AWC) and Percent area of significant coherence (PASC) now. How one could do it?

Hi Tatiana,

I understand that you want to calculate the average wavelet coherence (AWC) and Percent area of significant coherence (PASC) in MATLAB. You can follow the steps below:

1. Store the wavelet coherence results obtained from the Crosswavelet and Wavelet Coherence software into a matrix.
2. Load this data into MATLAB using the ‘load’ function.
3. Calculate the AWC by averaging the wavelet coherence values across all frequencies and time points using the ‘mean’ function.
4. Determine the PASC by calculating the percentage of significant coherence values above the threshold that you have set.

I hope this solves your query. Please refer to the documentation below for more information:

Load variables from file into workspace - MATLAB load (mathworks.com)

Average or mean value of array - MATLAB mean (mathworks.com)

Thank you very much for the answer Rijuta. I have already come to similar solution, but surely it will be helpful for others!
