Many thanks, Francois!
The data I processed is only phase-locked, not ERPs (both time-locked and phase-locked), so I want to:
- transfer all data from time domain to frequency domain (e.g., morlet wavelets),
- and then grand averaged.
- After that, I want to do ERD/ERS analysis on the source level.
However, I found that I cannot directly do source localization in the grand-averaged TF data ( frequency damain). So I tried to 1)compute source in each participant, and 2) then drag all participants data and follow the scout guide here:https://neuroimage.usc.edu/brainstorm/Tutorials/TimeFrequency. I used D-K scouts and frequency bands ( alpha, beta,etc). But 2) took really long. I wonder whether the process is correct. If it is not, could you please kindly help me?
Thank you very much!
