i want to perfom rossby wave detection using the wavelet coherence, but when i running the code there is always an error that says "error in wt.m time must be constant". when i change the year in the first clumn to numbers, the code runs. but when I include the first column as the years, the error massage appears. My data consists of 20 years,is there something wrong with my data?

hi nick,
I also experienced the same issue as shown in the image you sent when running my data. Coincidentally, the relevant script file is from the wavelet coherence, and I am using wtcdemo as the main script.
Here is the file, if the time column is replaced with regular numbers. This is what confuses me about the ‘formatts’ function.

Hi Sitti,
In the 'wtcdemo' file, it seems that 'boxpdf' is a user-defined function.
I am unable to reproduce the error, "error in wt.m time must be constant", due to the absence of code related to the custom functions. Could you kindly share the 'formatts' function file? You can use the following command in the MATLAB command window to find where the file is located:
which formatts %where formatts is the name of .m file
