Introduction This model of cell polarity shows the coupling of three model formalisms: A cellular Potts model with DirectedMotion that responds to cell polarity (but not directly to the external signal gradient), a co-moving PDE model on the membrane of the cell (to let cell polarity emerge from distributed receptor-signal interactions) and an external signal gradient (implemented as a global field with random fluctuations).

Pattern formation is robust to noise. Introduction Morpheus can also simulate ODE and PDE models with noise. One example (in the GUI menu Examples → ODE → LateralSignaling.xml) with coupled noisy ODE systems is explained in M0004.

Use logical operators and, or and xor in Condition for ChangeCellType. Introduction This example model demonstrates the use of logical operators. Please also see the built-in docu at GUI/Documentation/MathematicalExpressions.
