I am trying to find the spiking rates over 5 second intervals of time. I have the spike times of intervals in a cell array(spk). I am wondering if it is possible or if any of you clever coders might know of a way to set all of the intervals and spike times contained within those intervals to 0 to 5 second interval. For example, the spike time of the first interval in the cell is 59.031, so put that as 0.031. The next 59.0599 to 0.0599. Is this possible?
