Trackpy.link search range and memory #727

Open DaphneEPFL opened 1 year ago

DaphneEPFL commented 1 year ago

Hello, I am using TrackPy and I was wondering for the linking parameters if the search range increases with a higher memory. For example when the memory is 2, will the search range double after a missing frame?

In my case, I have a maximum displacement of about 10 pixels per frame and a memory of 200 frames. For my data I needed to set my search range higher than 10 to prevent the particle trajectory to be split into multiple trajectories. I would like to set my search range as low as possible to not have trajectories switch between different particles. It would help me to know if the memory parameter influences this search range.

Thank you in advance for your help!
