Hi, I'm trying to read data and integrate the results for a given bandwidth, something that I thought was going to be easy. the problem is that I cannot control the badwidth.
this is the code I am running, its a light modification from the one found on github.
when I run this code I get a sequence of images like this that gives me only a small region. How can I make the region wider? and how can i extract the average relative power like shown in the graph?
