Hi just wanted to bump this, I'm still interested in a response if anyone knows!
Hey sorry I missed this can you please post it on the python github and we'll answer there: https://github.com/MouseLand/suite2p
Ok!
Hi Carsen, Just wanted to make sure someone saw, but I posted the question here: https://github.com/MouseLand/suite2p/issues/267
Hello, I had a question regarding how to interpret the results of the python suite2p deconvolution. It's not clear to me what the y-axis of the deconvolution result means. Is the height of the spike suggesting that's the number of spikes occurring at that time point? That's what Step 3 from Figure 1 in this paper suggests:
On the other hand, I see others are thresholding the output to figure out when true spikes occur. Here another researcher on the MouseLand Issues page suggests as much: https://github.com/cortex-lab/Suite2P/issues/157 And based on the original OASIS paper, I notice on Figure 5, mentions of thresholding can be helpful. (To be honest, I'm not sure I understand if the output of the python suite2p is the same as L1 on this graph, so any clarification would be helpful.)
I'm overall confused because the amplitude of the spikes I'm getting are into the hundreds and thousands. Which makes me think I need to threshold. But if I threshold, I don't have an actual sense of how many spikes occurred nor can I be confident comparing spiking activity between cells/sessions.
