# How to define the settings for the simulations?

### Introduction

The graphics settings can be defined via the GUI, but most of them can also be defined in the project file, in the <SETTINGS> section. This is interesting for advanced users to pre-set the graphics.

### IIV

To pre-define the activation/deactivation of the iiv sections, the user can define it in a section <SETTINGS> and a subsection [GRAPHICS]. For that, two keywords are used iiv_parameter and iiv_covariate. By setting them at true or false, you can directly define if the iiv computations should be performed when running the project. In Mlxtran, activating both of them writes:

<SETTINGS>
[GRAPHICS]
iiv_parameter = true
iiv_covariate = true


If no covariate is used in the model, and the setting is iiv_covariate=true, then obviously no drawing of the covariate is made and the checkbox in the user interface is grayed. The same is done for the individual parameters.

### Percentile

To pre-define the values in the percentile tab, the user can define it in a section [GRAPHICS]. For that, three keywords are used: pred_interval, nb_band and nb_simulations for the level, the number of bands and the number of simulations respectively. In Mlxtran, defining 8 bands, a level of 90 with 200 simulations writes

<SETTINGS>
[GRAPHICS]
nb_simulations = 200
nb_band = 8
pred_interval = 90
