In the case of the second formula  plays the role of “regular” contact energy between cell and medium.
The syntax of this plugin is as follows:
0
-16
-16
-2
2.75
-1
Quadratic
0.0
2
Users need to specify ContactSpecificity ( ) between different cell types ContactFunctionType (by default it is set to Linear -  but other allowed key words are Quadratic -  and Min -  ). EnergyOffset can be set to user specified value using above syntax. NeighborOrder has the same meaning as for “regular” Contact plugin.
Alternatively one can write customized function of the two cadherins and use it instead of the 3 choices given above. To do this, simply use the following syntax:
0
-16
-16
-2
2.75
-1
Quadratic
0.0
2
J1
J2
sin(J1*J2)
Here we define variable names for cadherins in interacting cells (J1 denotes cadherin for one of the cells and cell2 denotes cadherin for another cell). Then in the Expression tag we give mathematical expression involving the two cadherin levels. The expression syntax has to follow syntax of the muParser - http://muparser.sourceforge.net/mup_features.html#idDef2.
