1. Introduction
This page contains a description of MATLAB scripts supporting the storage of DYON input and output data files in IMAS.
2. DYON output
The storage of the DYON output in IMAS is supported by two MATLAB functions, put_to_IMAS and get_from_IMAS. Depending on the situation, they can be integrated to the code or used separately as wrappers providing the connection between DYON and IMAS. The sample scripts test_put_to_IMAS and test_get_from_IMAS are provided, which illustrate how the functions are called.
The available IMAS Data Dictionary (DD) does not satisfy all requirements of DYON. Therefore, the functions put_to_IMAS and get_from_IMAS are to be extended after the planned extension of the DD.
Now the output data are placed into 7 IMAS IDS's (Interface Data Structures - sections of the IMAS DD describing tokamak subsystems or tokamak physics chapters): core_profiles, core_sources, equilibrium, gas_injection, magnetics, radiation, and wall (this list is to be extended). The allocation of the data in the IDS's and the functions supporting it are described below.

2.2. Running the scripts
To launch the test scripts, do the following:
1. Enter:
module load imasenv/<IMASversion>
Here <IMASversion> is 3.37.0 or higher.
2. The scripts in its present form use the IMAS database 'step'. If you are planning to use it and this database is non-existent, enter the following command to create the database:
imasdb step
You can replace 'step' with another IMAS database name, but do not forget to create it and change the variable 'machine' in test_put_to_IMAS.m and test_get_from_IMAS.m.
3. Enter either
matlab
or
matlab -nodesktop -nosplash
In the nodesktop mode, MATLAB should work faster (I did not notice big difference). Using the nodesktop mode, do not forget to run quit() to end the session (otherwise, a dangling MATLAB session may remain).
4. To save data from the available DYON output MAT-file, run test_put_to_IMAS.m (you can change shot, run, IDS comments etc. by changing the parameters in this script).
5. Type 'viz' (on a console with imasenv loaded) to see the content of the IMAS database.
6. To get the DYON output data back, run test_get_from_IMAS.m.
