find coordinates of a cell

[sessler]

I have not found the name of certain variables. To clarify why I need them, I will shortly describe my scenario.

This is a wound healing essay, where cells have two state: if a cell has 4 neighbors it will become quiescent, when it has less, it will transition back to proliferating cell. When 90% of cells have turned into quiescent cells, a scratch is introduced by deleting cells in the middle of the simulation area. After this, the simulation is continued for three more simulated days.

As I have read, the neighbor array is not used presently. I would need:

• the coordinates of a cell (I also need this to "inflict" the wound)
• and the variable, where the end of the simulation is stored.

Thank you. Judit Sessler

To obtain the coords of a cell, you can use pC->position[0] for X (and [1]=Y, [2]=Z) where pC is a pointer to a cell. Rf to various sample projects' custom.cpp that do this, e.g., predator prey.

For your primary goal of changing cell cycle based on # of neighbors, you might experiment with using simple_pressure (in the cell's state) instead of manually testing for # neighbors yourself. And in PhysiCell 1.11.0, you can use signals and behaviors and modify a cell cycle. See the interactions sample project's custom.cpp, for example, which does this (and more).

Thanks very much for the speedy reply!!!
