# Numerical simulations in tunacell¶

## Using the script¶

When installed using pip, a tunasimu executable is provided to run numerical simulations and save results on local directories. These files can be used to try tunacell’s analysis tools.

Such a command comes with various parameters, that will printed upon call:

\$ tunasimu -h


There is a list of (optional) parameters.

## What are these simulations about?¶

ou is the value of the Ornstein-Uhlenbeck random process simulated in each cell, int_ou is the integrated value of the random process reset to zero at each cell birth, exp_int_ou is the exponential of the later value. One can think of the Ornstein-Uhlenbeck as instantaneous growth rate of the cell, and thus exp_int_ou can be associated to cell length.
