how to relink trajectories from an existing trajectory dataframe

[alexlib]

Sometimes I get multiple broken trajectories and would like to run the linking again over the same data, preserving the existing particles and connecting previous trajectories into newer, longer trajectories.

Thanks for the great software.

Have you tried tweaking the memory and search_range parameters of tp.link in a way that could produce long enough trajectories ?

[alexlib]

Yes of course. Yet there are sometimes cases which are not connected and a second iteration might help. I just cannot figure out the right way to connect the existing trajectories. I could do it in manually by renumbering particles probably but I guess there is a better way.
