Cell width

[georgeoshardo]

Hi CellModeller team!

Is there a way to change the cell width in simulations? I believe at the moment all cells are the same width.

Hi Georgeos - there is a cell property "radius" (or "rad", not sure) that can be set in the same way as "length". best Tim

Thank you, I will try setting it again, but if I remember from my previous attempts at working with this attribute, it is not technically possible to, say, have the daughter of a cell be a different length to its mother upon birth, correct?

You can set any cell properties of daughters in the "divide" function. I wouldn't recommend changing the total length or the width very much as this could generate some big overlaps between cells and thus large forces.

Apologies for the late reply, I cannot find how to do this. No matter what I try, I cannot get cells to become wider within the simulation. Setting a new radius inside the divide function does not change the simulation output.

E.g

def divide(parent, d1, d2):
    # Specify target cell size that triggers cell division
    d1.targetVol = 3.5 + random.uniform(0.0,0.5)
    d2.targetVol = 3.5 + random.uniform(0.0,0.5)
    d1.radius = 1
    d2.radius = 1

If I print the radius at the beginning of the divide check loop, it always resets back to 0.5.
