How to draw a figure of averaging time periods?

Hi experts,

I would like to average the activation on a time period (e.g., 1s to 3s).I got a source-level brain activation figure. And this ERS/ERD figure was changed from each time point. I want to average on time periods. Could you please tell me how to do it!

Thanks a lot!

To average all the values on a given time window, use the process Average > Average time.
Be careful averaging values oscillating between positive and negative values over a long time, the average would be close to zero.

If you are not interested in the time dimension, you might be interested in using the PSD process to get the power over a time window of a few seconds, rather than computing a time-frequency decomposition and averaging along the time dimension.

Thank you for your suggestion, Francois!
