This project contains a library, as well as a front end application for spatial simulation of SBML Models (using SBML Level 3 with the Spatial package ). This project is made possible in cooperation with the Funahashi Lab who developed the simulator. (The initial presentation from COMBINE 2011 can still be found online here.)
This project uses CMake, as such building ought to be as easy as running:
mkdir build
cd build
cmake -DBUILD_UI=ON <directory with sources>
make
make install
Once installed, simply double click SpatialUI, and the following interface will come up.
From here, you could simply open one of the example models supplied. We use a custom annotation to store settings such as the last selected species, the colors used for them as well as the bounds. Of course you can open any model in the SBML Spatial format and define these settings yourself:
- Selecting the variables to plot: from the Palette Assignment panel, simply select the Species to display, choose one of the palettes distributed with the program, and define the maximum concentration (will be used to scale the palette). Next click 'add'. While it is possible to add multiple species that way I recommend to choose < 3 (and those in the palettes 'black-red', 'black-green' and 'black-blue' as that maps best to the RGB color scheme.
- Displaying Concentrations at a certain point: Simply click on a coordinate, and concentrations for all selected species will be displayed.
- Modifying the concentrations at a coordinate: First select the species whose concentrations you would like to change, next specify the concentration and enable the 'Apply' button. Then simply click / drag the mouse along the canvas to change the concentrations at those points.
Should you have further questions, or concerns please let me know.
I'm currently in the process of exposing the API through SWIG. A first prototype is available in the examples folder. To test it, compile with with the CMake option WITH_JAVA=ON, and then modify the example in examples/bindings to adjust the location of the sample file.
The API consists of these functions:
- SpatialSimulator ()
- virtual ~SpatialSimulator ()
- void initFromFile (const std::string &fileName, int xdim, int ydim, int zdim=1)
- void initFromString (const std::string &sbml, int xdim, int ydim, int zdim=1)
- void run (double endTime, double step)
- double oneStep (double initialTime, double step)
- void setParameterUniformly (const std::string &id, double value)
- void setParameter (const std::string &id, double value)
- int getXDim () const
- int getYDim () const
- int getZDim () const
- double getVariableAt (const std::string &id, int x, int y, int z=0)
Currently I'm also exposing these functions that I'm not happy about as they reveal too much about the underlying implementation. In addition they are not wrapped by the language bindings:
- SpatialSimulator (SBMLDocument *doc, int xdim, int ydim, int zdim=1)
- void initFromModel (SBMLDocument *doc, int xdim, int ydim, int zdim=1)
- const Model * getModel () const
- int getIndexForPosition (double x, double y)
- int getVariableLength () const
- int getGeometryLength () const
- void setParameterUniformly (variableInfo *info, double value)
- double * getVariable (const std::string &id, int &length)
- double * getGeometry (const std::string &id, int &length)
- boundaryType * getBoundaryType (const std::string &id, int &length)
- int * getBoundary (const std::string &id, int &length)
- double * getX (int &length)
- double * getY (int &length)
- double * getZ (int &length)
- void setGnuplotExecutable (const std::string &location)
- const std::string & getGnuplotExecutable () const
