Screen shot of the LNA implementation in COPASI. Screen shot of the COPASI graphical user interface and the linear noise approximation task. Shown is the resulting covariance matrix of species' particle numbers in the p38 MAPK model by Hendriks et al. . The matrix is colour coded, positive values have a green background and negative values a red one with intensities corresponding to the absolute values.
