Thank you for bringing up this issue.
I edited the code of the spectrum normalization process to include:
- a warning in the process options:
- a warning in the report if there are overlapping frequency bands in the input file:
Git commit: Added warning for relative power with overlapping freq bands · brainstorm-tools/brainstorm3@a570450 · GitHub
Simply update Brainstorm to get this fix.
Are these warnings clear enough according to you?
