DynaSys Files

DynaSys, by Matt Phillips

The executable is in the build-DynaSys-.../release folder.

0.4.0: Most significantly, added the ability for the user to enter in equations for nullclines and the jacobian matrix.  When these are present, nullclines can be calculated with much higher resolution and fixed points can be identified and classified.  In addition, added the ability to create and save variations on a particular model, wherein different inputs parameters and input files are associated with a single model.

0.3.1: Bug fixes, refactoring, and the addition of the 'Event Viewer' gui.  This lets you define 'events' as occurring whenever a variable crosses a threshold (either from above or below) and calculates events per unit time as well as a density function.  This is most obviously used for neural data but works for any signal that has discrete events.  The facility for using DynaSys to model user data has also been improved dramatically.

0.3.0: Numerous bug fixes and many new features in this version.  Most significantly, you can now auto-generate a CUDA kernel and accompanying Matlab interface code, and run simulations on a GPU.  You can add in your own objective (cost) function to fit parameters.  Example objective functions can be found in the 'Measures' subdirectory.  Matlab code for fitting, 'FitDynaSys', is included.  Now also a 'Variable Viewer' mode to view variable (function) values as a function of dynamical state.

0.2.0: You can now generate a Matlab MEX file which can be compiled and run from within Matlab, as well as a 'helper' m-file do do this.  If you compile under Linux, you can compile and run the model as a standalone C program.

Source code can be found in the repository.  To load an input file, set the file name as a variable in quotes, e.g. "C:/Users/matt/myinput.txt" for a text file or "C:/Users/matt/myinput.dsin" for a binary file.  See example files in DynaSysFiles for the format for the case of text files.  To get the binary file format see input.cpp, Input::LoadBinInput.
