Artifact cleaning with SSP

Hi Francois, and Brainstormers

Hope you're doing well,
I have one question about the artifact removal. after I detect the heartbeats, I could n't select the menu: "Artifacts > SSP: Heartbeats". as below. the button is gray, how should I do?because I follow the tutorials. It show difference.

Thank you.

Could it be that you are trying to use SSP on an already imported data file?
