6.2 Importing files

The file importer is initiated automatically when the data module is accessed. Otherwise, it can be accessed by clicking “Open setup” in the Settings card.

 

Supported data types

Currently, two import file types are supported:

  • ASAM-ODS ATFX files, in the XML-based ASAM Transfer Format (ATFX). The header file (*.atfx) and the data file(s) must be located in the same folder level in the directory.
  • MATLAB MAT-files with a layout originating from:
    • A DIRAC export
    • An export of the VIBES Toolbox for MATLAB. This needs to be an export of an FRF matrix object using the native formatting option, e.g. save(‘filename’,’-native’)

 

Import files

Files are imported by dragging the ATFX header file (*.atfx) or MAT file into the importer. By default, the full list of impact measurements will be imported. By right clicking on the measurement names, measurements can be removed from the import using “Delete” or “Delete All”.

 

Map channels / excitations

Here the channels and excitations in the imported data are mapped to channels and excitations in your DIRAC project (defined in the Prepare module). Select the sensors/channels/excitations on the left and drag them onto the correct FRF channels on the right to define the mapping. Multiple channels and sensors can be mapped simultaneously, as long as care is taken to ensure the same ordering between the DIRAC channels and FRF data.

Mappings can be deleted by right-clicking within the sensors/channels/FRF channels and clicking “Delete” or “Delete All”.

 

In the following videos it is explained how to import files and map channels and excitations.
