KaSim is a stochastic simulator for rule-based models written in Kappa. A pdf of the reference manual is available here; the latex sources are available in the man/ directory.
To install you need the ocaml native compiler. To check whether you have it, type
ocamlopt.opt -version
Ocaml native compilers can be downloaded on INRIA's website. To create kaSim binaries, simply type
make
This should produce KaSim binaries. You will need your own plotting program (like gnuplot) to visualize curves.
In order to run a simulation of 1000 rule applications, type
KaSim -i kappa_file -e 1000 -p 1000 -o data_file
This will produce a data file of 1000 point (-p option) containing the trajectory that was produced during the simulation.
Type:
KaSim --help
for a complete list of options.
