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 compile KaSim, you need the ocaml native compiler versoin 4.01 or above and the findib library. To check whether you have them, type
ocamlfind ocamlopt -version
If you use a package manager (or opam, the Ocaml package manager), Ocaml compilers and findlib are really likely provided by it. Else, Ocaml native compilers can be downloaded on INRIA's website. The Windows bundle contains findlib. Findlib sources are available on camlcity.org.
To create kaSim binaries, simply type
make bin/KaSim
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
bin/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:
bin/KaSim --help
for a complete list of options.
