Hi, I identified all the blinks and heartbeat in my eeg file. I was wondering if I need to identified them as bad to make sure they are excluded from the further analyses or if just by marking (as an event) is enough for brainstorm?
Thank you
Hi @mmbriand
Marking blinks and heartbeat as bad is not a good idea, and marking them as events will not change anything on the processing.
Please refer to the online tutorials, in particular, this one:

Hi @tmedani,
thank you for your answer. I followed exactly what is described in the tutorial-artefactsDetect. It means I don't understand something, How is it possible then to pass from identify the artefacts to use the EEG for analyses without the artefacts (or at least considereing the artefacts).
Thank you
Then this is a good starting, it was not clear form your previous post.
After defining these segments, you need to follow the next tutorial:
https://neuroimage.usc.edu/brainstorm/Tutorials/ArtifactsSsp
and in particular the ICA part: https://neuroimage.usc.edu/brainstorm/Tutorials/Epilepsy#Artifact_cleaning_with_ICA
Marking blinks and heartbeats is useful if you are using artifact removal methods such as SSP (https://neuroimage.usc.edu/brainstorm/Tutorials/ArtifactsSsp). If you use ICA, the blinks and heartbeats are not used.
Before using your own data, try following the Get started tutorials with the provided data, so you get familiar on reason to be for the steps and then you can decide if they apply or not to the processing of your own data.
