I’m processing MEG data in Brainstorm3 (Matlab2019b) and am unable to access the SSP: Heartbeats and SSP: Eye blinks options, which remain greyed out despite having completed the expected prerequisite steps. My pipeline so far is: raw file → notch filter → band-pass filter.
I opened the resulting “raw | notch | low file” in the Record viewer, identified the ECG and EOG channels, and ran Artifacts > Detect heartbeats + Artifacts > Detect eye blinks within the viewer. Events panel shows cardiac (x459), cardiac2 (x114), blink (x77), blink2 (x11), blink3 (x11), blink4 (x7) events with the correct lowercase labels. Despite this and that event names match the expected labels, both SSP options remain greyed out and unclickable. I’m unsure whether this could be related to a plugin conflict, a restriction on running SSP on filtered derivative files rather than the original raw, or something else entirely.
Could you help me understand what might be preventing SSP from becoming available?
