I'm a new user of Brainstorm.
I am currently trying to compute de PSD (Welch) on an ERP, to observe the effects the averaging on the frequencies of the signal (i.e does it delete the 50Hz power line noise, etc...).
However, I am not familiar with the algorithm, and despite the tutorial information, I cannot find a proper window length for the computation. My ERP length is 350 ms (-50 ms to 300 ms).
Would it be possible to get some additional information about how to chose this window length depending on the data of which you want the PSD?
Thank you in advance.
