MYRIAM is an open-access, computationally-inexpensive, user-friendly software that allow users to compute the torque variations required to produce given changes in plate motions.
To download a pre-compiled version of MYRIAM, go to the Releases page and select the latest version. Under the "Assets" section, download the appropriate file for your operating system. Once the download is complete, unzip the file and move the folder to the desired location.
To download the latest version of MYRIAM from a specific repository branch (e.g. main), copy the following commands into your terminal:
cd /path/to/desired/directory # Directory where to clone MYRIAM
git clone https://github.com/ValeEspinozaF/MYRIAM.git
cd MYRIAM
git checkout main # or whichever branch is preferred
git pull # fetch all recent changes from this branchAlternatively, you can download the latest version of MYRIAM as a ZIP file from the GitHub repository. Under the repository name, click on the blue button that says "Code" and select "Download ZIP". Once the download is complete, unzip the file and move the folder to the desired location.
MYRIAM calculations run as a self-contained release, and require no additional dependencies. However, to generate PNG figures you will need Python and the following packages:
- Python 3.8 or later
- Pandas 1.4.4 or later
- Matplotlib 3.5 or later
- Cartopy 0.18.0 or later,
- and dependencies therein*
*Note that Cartopy up to version 0.21.0 may encounter package issues when importing, particularly lgeos. Make sure to install/downgrade Shapely to its version 1.8.5 to avoid the above issue.
See the Manual for an example on how to use MYRIAM to achieve refined results in a time-efficient manner. All necessary files to run the examples are included in the examples folder.
You can also find examples of MYRIAM (or the base algorithm) used in plate motions research:
