Hi @GiacomoBertazzoli

It can be complicated for the FEM in this case.

One solution is to follow the same instructions as in this topic:

OpenMEEG BEM: WARNING: 239 dipole(s) outside the BEM layer "Brain"

Thank you very much! I have one last question: after computing source, I did PSD (Welch) estimation based on source data, and then projected those PSDs to group analysis. However, the matlab window prompted: Warning: This source file was not computed based on a template grid. Did I miss any step? Best, Liwei

Let me know how it goes.

Best,
