LiNA -- A graphical MATLAB tool for analyzing intrinsic noise in biochemical reaction networks
LiNA provides a simple, but easy-to-use, GUI from within MATLAB running under R2010b or higher. In its current form it comprises the following features:
- calculates the variance-covariance matrix for mass-action networks under steady state conditions based on the linear noise approximation of the chemical master equation
- automatically detects and takes care of conservation relations in the network
- parameter scans for the mean values and stochastic quantities such as the Fano factor, the coefficient of variation and correlation coefficients
- allows to define parameter combinations as new parameters (e.g. to analyze the Fano factor as a function of a dissociation constant rather than separately for forward and backward rates)
- allows to calculate stochastic quantities along different stable branches in bistable systems
- easy export of plots as MATLAB figure for further processing
- 12/2014: New version of LiNA (v1.1) has been released which contains minor bug fixes.
(Thanks to Qurat-Ul-Ain Azim for his bug report.)
LiNA has been developed by Bastian Hagel, Axel von Kamp and Ronny Straube.
Unzip the Lina_v1.1.zip archive to your HOME directory which will create the directory LiNA_v1.1
Startup MATLAB and change to the LiNA directory. Type 'startlina' at the console.
Note that LiNA requires the 'Symbolic Toolbox' of MATLAB.
