Hello Brainstorm forum!
I am new to MEG preprocessing/brainstorm, so bear with me. For some background, I went through the first half of the brainstorm tutorials with my own data. The participants had their eyes closed during the recording, so saccades were the main eye artifact generated. I followed the tutorial's suggestion for removing saccades (detect other events --> rename the 1-7 Hz artifacts saccades --> remove saccades with SSP). The first SSP component was the only component that reflected eye movements, so it was removed. After the removal, an artifact was left at the beginning/end of some of the saccades (highlighted in the image below). Did I do something wrong when removing the saccades? Is there any way I can remove these "steps" in the data, or will I have to mark all trials with these artifacts as "bad"?
Thank you all!
