Hi, MNE experts,
I delete the first problem because I notice that the first problem is not a big issue. I just need a list of volume source estimates， so I just need to append them to an empty list.
Another question is I use a 0.1~40 Hz filter for data preprocessing(for beamformer source estimate), I notice that some articles use a relatively broad filter band (for example, 2~80Hz or 0.1~200 Hz). So is this filter band (0.1~40) too narrow for beamformer estimation? or are there any suggested filter band or data preprocessing steps for LCMV source estimation?
Best wishes！
