To delete a study definition, you need the 'Delete study' permission
Only studies with the status of 'In Preparation' can be deleted. The current status of a study can be viewed in the list of studies or from within the study via the Study Details tab.
From the File menu, select Delete Study.
If you have a study open, it will be assumed that this is the study that you want to delete.
If you do not have a study open, the list of existing studies will be displayed. Select the study that you want to delete and click OK.
You will be asked to confirm the deletion. Click Yes to delete the study, or No to abort.
You will be informed when the study has been deleted.
When you delete a study, any user roles that were associated with it in the System Management module will also be deleted. If you reinstate the deleted study (by importing a copy of it), you will have to re-create the user roles again.
