6.2 Loading operational data

The Operational Data card shows basic information for all imported data, such as name, status (if imported or loaded), type, size, duration and test assembly.

Importing and loading data

SOURCE uses a “lazy loading” procedure that allows the user to import the data’s header information before actually loading all of the (potentially very large) data. Thus, we have a two-step process to get the data into the workspace:

  1. To import data, simply drag and drop the desired operational data file(s) into the Operational Data card. While the data is being imported, the taskbar on the bottom will show you the progress of the operation. When the task is finished, “Idle” will appear in the task bar, and the file information will appear in the Operational Data card along with a gray status indicator to show that the data have not been loaded yet.
  2. Next, the data have to be loaded. This is required each time you re-open your SOURCE project, as the data are not stored locally. To load the data, right click on the desired file and press “Load data”, as shown in the figure below. 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”.

Grouping operational data

When a project contains multiple operational data, it is often useful to group them such that the desired analyses can be performed on the entire group using a single set of parameters. To do so, select all the operational runs that should be grouped, right click on them and select “Group”, or use key command CTRL-G. The group name and test assembly can be edited in the Details card.
