            # Cytosim

Cytosim is an [open-source](LICENSE.txt) cytoskeleton simulation suite designed to handle large systems of flexible filaments with associated proteins such as molecular motors. It is a versatile base that has been used to study actin and microtubule systems in 1D, 2D and 3D. It is built around a cross-platform C++ core engine running on UNIX, Mac OSX, GNU/Linux and Linux-environments within Windows. The code is modular and extensible, making Cytosim a convenient base that can be customized to meet particular tasks. Some of the most common tasks encountered during a simulation project are implemented in Python.

Cytosim has been used for about 100 research articles from the [Nedelec](doc/publications/index.md) and [other groups](doc/publications/biblio.md).

![Cytosim](doc/data/cytosim.png)

Cytosim is a suite of command-line tools with simulation and display capabilities. The simulation is specified in a [configuration file](doc/sim/config.md), defining objects with their parameters and a suite of operations, such as advancing time, saving frames or [generating reports](doc/sim/report.md). Here is a basic example, with parameters specified in [units of seconds, micrometers and pico-Newtons](doc/sim/units.md).

	set simul system
	{
	    time_step = 0.005
	    viscosity = 0.02
	}
	
	set space cell
	{
	    shape = sphere
	}
	
	set fiber microtubule
	{
	    rigidity = 20
	    segmentation = 0.5
	    confine = inside, 200, cell
	}
	    
	new cell
	{
	    radius = 5
	}
	
	new 5 microtubule
	{
	    length = 11
	}
	
	run 5000 system
	{
	    nb_frames = 10
	}

# Documentation

[Link to documentation](doc/index.md)

The Brownian dynamics approach was described in:  
[Collective Langevin Dynamics of Flexible Cytoskeletal Fibers](http://iopscience.iop.org/article/10.1088/1367-2630/9/11/427/meta)

The documentation source files use [Markdown](https://en.wikipedia.org/wiki/Markdown) and are best viewed with [MacDown (Mac OSX only)](https://macdown.uranusjr.com) or [Typora (Cross platform)](https://typora.io) 

# Installation

Cytosim is distributed as source code and [must be compiled](doc/compile/index.md) before use. On Mac OS X and Linux this should be uncomplicated even if you are not familiar with program development. Compiling natively on Windows would require changes to the code, but Cytosim should compile with the [Windows Subsystem for Linux](doc/compile/wsl.md).

To download the source code, enter these commands in a terminal window:

	git clone https://gitlab.com/f-nedelec/cytosim
	cd cytosim
	
To compile using [make](https://www.gnu.org/software/make), try:
	
	make

If this fails, parameters of `makefile.inc` need to be updated manually.
Altermatively, it is possible to use [cmake](https://cmake.org) to configure `make` automatically:

	mkdir build
	cd build
	cmake ..
	make

For troubleshooting, please check [the compile instructions](doc/compile/index.md).
Once *cytosim* is running on your machine, proceed with the [tutorials](doc/tutorials/index.md), the page on [running simulations](doc/main/runs.md), and the examples contained in the folder `cym`. 
Inspect in particular the short configuration files (e.g. fiber.cym, self.cym).
