OCEANLYZ, Ocean Wave Analyzing Toolbox, is a toolbox for analyzing the wave time series data collected by sensors in open body of water such as ocean, sea, and lake or in a laboratory.
OCEANLYZ GUI is a graphical user interface for the OCEANLYZ toolbox.
This toolbox provides spectral and zero-crossing wave analysis. It can calculate wave properties such as zero-moment wave height, significant wave height, mean wave height, peak wave period and mean period. This toolbox can correct and account for the pressure attention (pressure loss) in the water column for data collected by a pressure sensor. This toolbox can separate wind sea and swell energies and reports their properties.

To use stand-alone GUI version of OCEANLYZ (Microsoft Windows (64-bit)):
Download OCEANLYZ GUI setup file:
Run setup file and follow setup wizard to install OCEANLYZ GUI
Start OCEANLYZ GUI
For documentation, use Help menu in OCEANLYZ GUI
To use MATLAB version of OCEANLYZ toolbox:
Install MATLAB or GNU Octave
- MATLAB: https://www.mathworks.com
- GNU Octave: https://octave.org
Download OCEANLYZ:
- Version 2.0 (GitHub): https://github.com/akarimp/Oceanlyz/releases/download/2.0/oceanlyz_2_0.zip
- Version 1.5 (CNET): https://download.cnet.com/Oceanlyz/3000-2054_4-75833686.html
- Version 1.5 (GitHub): https://github.com/akarimp/Oceanlyz/releases/download/1.5/oceanlyz_1_5.zip
- Version 1.4 (GitHub): https://github.com/akarimp/Oceanlyz/releases/download/1.5/oceanlyz_1_4.zip
Unzip OCEANLYZ in any location you choose such as “C:\”
Add OCEANLYZ folder to MATLAB or GNU Octave path
For example, if OCEANLYZ files are in "C:\OCEANLYZ" folder, then:
To add OCEANLYZ to MATLAB or GNU Octave path, run following commands in the Command Window:
OceanlyzPath = genpath('C:\oceanlyz'); %Generating path for OCEANLYZ folder and its sub-folders
addpath(OceanlyzPath); %Add OCEANLYZ folder to pathMATLAB users need to install MATLAB Signal Processing Toolbox (https://www.mathworks.com/products/signal.html) for running the OCEANLYZ spectral analysis. It gives OCEANLYZ access to MATLAB Welch's power spectral density calculation. However, MATLAB Signal Processing Toolbox is not required for zero-crossing analysis.
GNU Octave users need to install/load GNU Octave Signal package (https://gnu-octave.github.io/packages/signal) for running the OCEANLYZ spectral analysis. It gives OCEANLYZ access to GNU Octave Welch's power spectral density calculation. However, GNU Octave Signal package is not required for zero-crossing analysis. To find the list of the GNU Octave's pre-installed packages, run the following command in the Command Window:
>> pkg listGNU Octave comes with Signal package but it needs to loaded every time GNU Octave starts. The Signal package can be loaded inside GNU Octave by running the following command in the Command Window (This should be done every time GNU Octave is opened):
>> pkg load signalIf GNU Octave Signal Package is not already installed, it should be first installed from https://packages.octave.org, and then get loaded by running the following commands in the Command Window:
>> pkg install "https://downloads.sourceforge.net/project/octave/Octave%20Forge%20Packages/Individual%20Package%20Releases/signal-1.4.5.tar.gz"
>> pkg load signal- Open MATLAB or GNU Octave
- Change a current folder (current directory) to a folder that contains OCEANLYZ toolbox, for example “C:\oceanlyz”, in MATLAB or GNU Octave.
- Open a file named “oceanlyzinput.m” in MATLAB or GNU Octave editor and modify it based on the properties of the collected dataset and required analysis.
- Run a file named “RunOceanlyz.m” in MATLAB or GNU Octave to start calculations.
To use Python version of OCEANLYZ toolbox:
- Install Python
- Install OCEANLYZ
1) Install Python
First, we need to install Python programming language.
- Method 1:
- Install Python from https://www.python.org and then use the pip command to install required packages
- Method 2 (Recommended):
- Install Anaconda Python distribution from https://www.anaconda.com and then use the conda command to install required packages
2) Install OCEANLYZ
After Python is installed, you need to install OCEANLYZ package.
If you installed Python, then you need to install OCEANLYZ via pip (https://pypi.org/project/oceanlyz). To do that, open the Command Prompt (or Terminal) and run:
pip install oceanlyzIf you installed Anaconda Python distribution, then you need to install OCEANLYZ via Anaconda cloud (https://anaconda.org/akarimp/oceanlyz). To do that, open the Command Prompt (or Terminal) and run:
conda install -c akarimp oceanlyzFollowing packages are required:
- NumPy (https://numpy.org)
- SciPy (https://www.scipy.org)
- Matplotlib (https://matplotlib.org)
- Open Python
- Import OCEANLYZ package by using "import oceanlyz"
- Create OCEANLYZ object such as “ocn=oceanlyz.oceanlyz()” in Python and set/modify its properties based on the dataset and required analysis.
- Run a method as “ocn.runoceanlyz()” in Python to start calculations.
OCEANLYZ code can be run on Microsoft Windows, Mac, and Linux. However, make sure any given path is compatible with a running operating system. In particular, “\” is used in Windows path, while “/” is used in Mac or Linux path. For example, if a path is “C:\” on Windows machine, it would be “C:/” on Mac or Linux.
OCEANLYZ GUI can be run on Microsoft Windows (64-bit) machine.
OCEANLYZ toolbox can be run by using MATLAB (https://www.mathworks.com), GNU Octave (https://octave.org), or Python (https://www.python.org).
