4.7.5 Wavelet transform

Mingsong Li edited this page Mar 7, 2019 · 2 revisions

This wavelet analysis function conducts wavelet analysis (Torrence and Compo, 1998) with user-defined parameters.

Steps:

1. Select a data file in the Main Window

Warning: The data file must be an evenly spaced depth/time series.

2. Select Timeseries --> Wavelet Transform menu

3. Modify parameters

  • Period ranges from [the first line] to [the second line] unit.

    Default values for all values work well with the program.

  • Users may need to modify the period range in the 2nd line using a smaller number (e.g., halved value).

Stand-alone versions of Acycle may have bugs in the wavelet transform
