Users have the option to sign a study, which subsequently signs all experiments contained within the study at once. Navigate to the Studies page and click the View icon to open the study information sheet.

Click the Sign button. 

In the pop-up window, a list of all experiments within the study that can be checked for signing is displayed. Enter your credentials and click Sign Experiments to sign and lock all selected experiments in the study. Experiments that are already signed will not be listed.

Note that studies can currently only be signed when a single signature is required to sign and lock an experiment. When the witness signature option is active, each experiment in the study must be signed individually by the witness.
