This tutorial subsection presents an example of loading IMAS IDS case within IMASViz and opening one of the IDS nodes.
1.1.1. 2.1 Loading IMAS IDS
The procedure to load the IDS is as follows:
- In the main IMASViz GUI, select the first tab - Local data source.
Enter the following parameters, listed below, to the appropriate text fields.
Tutorial IDS case parameters:
User name: g2lfleur
IMAS database name:test
Shot number:52344
Run number:0
By default, the data source is a pulse file located in $HOME/public/imasdb/<IMAS database name>/3/0/ directory. In this case, the ~public/imasdb/test/3/0/ directory of user g2lfleur.

The procedure of opening any IDS is the same. In this tutorial, the procedure will be shown on magnetics IDS
- Click button Open.
A navigation tree window will open, as shown in the figure below.
- Press the '+' button on the left side of the IDS root. This will expand the navigation tree window and display a list of all IDSs. Available IDSs for the given shot are displayed in blue.
The tree will allow browsing data for the specific shot number which is displayed by the root node ( IDSs(52344) ). - Open 'magnetics' IDS by right clicking on 'magnetics' node and selecting the command Get magnetics data (default to occurrence 0) as shown in the figure below.
The magnetics IDS nodes are displayed as new nodes in the tree, as shown in the figure below. Nodes of an IDS are organized according to the IMAS
data dictionary.
