In the ELN, there are two options for linking experiments to one another. Users can either link an experiment at the section level, or link an experiment at the experiment level. 

To link an experiment at the experiment level, click the Link button.

In the pop-up window, you can navigate to the experiment and click Choose experiment to create the link. 

The link will be visible in both linked experiments .

The other option is to open a text, procedure, or comment section and click the Link experiment icon.

Next, you can browse through your projects and studies to find the experiment you want to link. Click Choose Experiment to insert the link for the selected experiment into your text section.
