GNU MCSim

GNU MCSim is a simulation package, written in C, which allows you to:

GNU MCSim and R (even under Microsoft Windows)

The basic tools needed to build and run GNU MCSim are not available to most users of Windows systems.
Fortunately, the R software (see http://www.r-project.org/), when properly installed with its Rtools (this requires administrator's rights), can compile and run GNU MCSim models. We have developed code and R scripts to compile GNU MCSim models to C code usable by the R package deSolve (to do that use the GNU MCSim "mod" model generator with the -R option) or by itself. This works under any operating system. You can then use deSolve to perform simulations of your models. The integators provided by deSolve are improved implementations of the lsode family of integrators (used also by GNU MCSim), and provide a few more options than GNU MCSim (in particular, "events", see the deSolve user manuals). However, if you need raw speed (say, for Markov chain Monte Carlo simulations) GNU MCSim is the fastest option.

Follow this link to download the corresponding scripts and code.

You need to have R and its Rtools (and optionally the deSolve package) installed.

Downloading GNU MCSim

The latest version of GNU MCSim (5.5.0) can be found on the main GNU ftp server: http://ftp.gnu.org/gnu/mcsim/ (via HTTP) and ftp://ftp.gnu.org/gnu/mcsim/ (via FTP). It can also be found on the GNU mirrors; please use a mirror if possible.

The gzipped tar archive contains:

Older versions can also be obtained on the GNU ftp mirrors and main page.

GNU MCSim development is hosted on savannah.gnu.org. See the MCSim project page on Savannah, where the latest development sources are publicly available.

Documentation

The User's manual for GNU MCSim is available online, as is documentation for most GNU software. You may also find more information about GNU MCSim by running info mcsim, or by looking at /usr/share/mcsim/doc, or similar directories on your system.

Check also the User's Manual update file provided with the source code for last minute updates and tips.

Installation

To install GNU MCSim, you will need a C compiler and linker to compile the sources and obtain executables. For any machine we recommend the GNU gcc compiler, but standard C compilers should also work.

Versions 5.0.0 up to 5.3.1 required GNU Scientific Library (gsl) to be installed. With version 5.4.0, GNU gsl becomes optional (but recommended).

Versions above 5.4.0 also prefers libSBML v4.2.0 or above to be installed, but that is not needed if you do not want to read SBML model files.

The user's manual (online here) provides detailed instructions for installation for several platforms.

Mailing lists

GNU MCSim has the following mailing lists:

Announcements about GNU MCSim and most other GNU software are made on info-gnu (archive). See also info-mcsim.

Security reports that should not be made immediately public can be sent directly to the maintainer. If there is no response to an urgent issue, you can escalate to the general security mailing list for advice.

You can also look at the same lists, GNU MCSim help, and GNU MCSim bug report, on the gmane portal which has spam control.
