Downsampling cnmfe parameters in initialization

[zhouyi0812]

Hello!

I have a question about the downsampling parameters. I wonder if it is always good to select 1 when my computer has enough memory? Since each time if I choose parameters=1 it took so long to run per movie maybe 2 hours.

I also tried to downsampling to 2 and the different between 1 and 2 I saw is the number of ROIs. Will it impact the quality of the traces?

Thank you!
