Hello, I’m trying to use the 2P dataset for my own project, but I have some questions about the experiment design.
As shown in the picture, the “go trial” means the images changed, but I don’t fully understand the “catch trail”. If it means the images have no change, the first several trials in the “go trial” should also means the “catch”; and the end of the “catch trial” is also a “go” because it has a image change.
So I want to know how the define the “go” and “catch” trial. Are they exist in the mice’s behavior experiment or just in the data analysis? Are they distinguish because of the number of non-change images?
I am bringing this up because I found the number of “go trial” and “catch trial” does not meet my expectations when I looked at the performance data. I used to think that every image’s onset means a trial, changed image corresponding to a “go” trial and non-changed image corresponding to a “catch” trial. If it’s true, the “catch” number should much larger than the “go” tiral. So I guess you have already defined the “go” trial and “catch” trial in other ways, and I wonder the specific definition.
