Sweep_response calculation and relationship with DF/F

Hi all

I’m trying to pull out the neurons tuning curve to the drifting grating stimulus from Allensdk, and I get the heatmap but get confused about the DF/F %, maybe this is a very novice question. But I would be very grateful if anyone knows what does the % sign mean? I track the Allen’s code and find out the value calculated is from the sweep_response, I’m wondering how the sweep_response is calculated and is it related to the raw df/f trace?


I think I replied to this in part here:

In brief, the sweep response is not computed from the df/f trace, but the DF/F is computed for each trial from the correct fluorescence trace.

Let me know if you have more questions about this.
