Yes, But you need to subtract the average signal (ERP) of each condition from their corresponding trails before computing the connectivity. We have this option in Brainstorm (remove evoked response).

Dear @hossein27en,

What is the reason for subtracting the average signal (ERP) of each condition from their corresponding trails before computing the connectivity?

I look forward to your reply.
