RecursionError: maximum recursion depth exceeded in scf.tl.slide_cells

[willey2020]

Hello! Thank you again for this great package!

While trying to separate cell windows using scf.tl.slide_cells,

scf.tl.slide_cells(adata_ted,root_milestone="A",milestones=["B","C"],win=110), it shows:

---

RecursionError: maximum recursion depth exceeded while calling a Python object

I try to debug and it seems that the after about 15 cycles the parameters are not change any more but the recursion keep going until 10000 times that hit the maximum system limit and stopped.

Could I ask what the potential problem is here? Thank you!

This was due to the algorithm being stuck at the end of a segment if only one node was taken in account for cell assignment, it is now fixed in v1.0.6.

Works perfectly! Thank you so much @LouisFaure!!!
