I'm trying to cut the raw file to the length I want using Metavision Studio, but the problem arises here. When I specify the length I want (for example, 2s), most of the time it gives me a value that doesn't match, like 2.003s or 1.973s. I guess this is because there are no events that occurred in 2s? Then, is it impossible for me to cut the raw down to exactly 2s?
