A similar process is used for loading and plotting FRF data as with the operational data. The FRF Data card shows basic information for all imported data, such as name, status (if imported or loaded), type, size, and bandwidth.
You can import FRF data in two ways:
DIRAC file importer
You can directly import a DIRAC project in SOURCE, without previously exporting it. During the import, an import dialog will appear, in which you can select the desired datasets from all the matrix presets. You can also import geometries, and define and review the channel types that are based on the Description field of the senors and excitations. A time block dataset is optionally added to the Operational Data module, with the raw time data of the impacts.
If the FRF data are loaded from a DIRAC project (export) specifically, several FRF datasets may be available within a single file. The nomenclature used for the names of these datasets is the following:
The types of data available in the specific file will depend on how the export settings were chosen in the DIRAC project.
SOURCE uses a “lazy loading” procedure that allows you to import the data’s header information before actually loading all of the (potentially very large) data. To load the data, right-click on the desired file and press Load data. When it is loaded, the status will turn from grey to green. It is also possible to unload data by right-clicking on the file and selecting Unload data.
