Example model files for Magrathea

From irefindex

How to use these example files

For Windows

1. Download a copy of breve from http://spiderland.org. These examples have been tested using breve 2.7.2.

2. Obtain a copy of magrathea.tz.

3. Copy and paste any one of the examples below to a file named model.txt and move to the same directory as magrathea.tz

4. Double click on breveIDE.exe to start breve.

5. Under the File menu, choose Open and then choose magrathea.tz

6. Hit the "play" button on the bottom of the breve interface.

More help with breve is available at http://spiderland.org.

Example 6.2


###########
#rules.2.txt
#This demonstration shows a somewhat more complex use of rules to 
#demonstrate the process of lateral signalling.
#In this example, a ligand molecule binds to a membrane-bound receptor.  
#On binding, the receptor changes state (becomes activated) as indicated by 
#a colour change.  The receptor in this new state also gains the ability to 
#bind to and activate other membrane bound receptors.
#
#No new concepts are introduced in this model compared to the rules.1.txt
#example so there are few comments in the file.
#See the "Making Models" section of the Magrathea manual for more details
#on the syntax of each line
# 
#after a molecule x changes state, molecule x and all molecule types that might be coordinated 
#in some coordinator with molecule x have there neighborhood size reset
#turn on #show-neighbor-lines 1# to see how this happens

#In this example, blue molecules (ligand) bind to a surface receptor (black) and are

#rules.4.txt
#
#translocation demonstration
#In this example, a blue particle (ligand) binds to a surface receptor and is translocated past the
#membrane (mediated by the black receptor) where it changes color to yellow.  
#Once on the other side of the membrane, the particle may then bind a second
#receptor (grey) that translocates it back to the top of the membrane
#Use of the two different receptors for translocation "in and out" is controlled by
#a feature-state pair.
#Planar coordinators are not compartments in the sense that molecules can move in and out of them.
#Instead, they represent barriers within a compartment (in this case the simulation)
#that molecules can move past with the help of a mediator molecule (the black and grey receptors).
#
#See the "Making Models" section of the Magrathea manual for more details
#on the syntax of each line
# 
#last tested with breve 2.6.1 and magrathea.tz 1.44
#at the time of testing, neighbor lines are only drawn if breve 2.5 is used
