- From the options appearing for Design, select Data Sources.
Here you can add or remove data sources from your study as the study requirements changes. To add a new data source, click on Add New Data Source:
This will open the Add a new data source dialog, which shows all available data sources, that is not yet added to your study. Selecting any data source from the list shows a short description of the data source as well. You can read a more detailed description on Data Sources section. You also can select whether a given data source should be mandatory or optional, as described in Create New Study section.
Pressing Add will add the selected data source to the study. Any participants joining in future will provide data from this data source as well. Keep in mind if there are currently enrolled participants in the study, you need to update their device.
To remove a data source, simply click on the trash icon next to each data source. This will ask for a confirmation prior to removing the data source from the study.
Removing a data source from a study does not delete the data collected so far from that source. It only stops collecting new data from the source. You need to manually remove the collected data if necessary.
Currently, there is no option to edit a given data source (e.g. changing it to mandatory or optional). If you need to modify a given data source, simply remove it, and add it again with the modified settings.
