# Model  Initialization and Visualization

You can download the XML specifications for this model here:

{% file src="/files/m7cnVep6q74jfjvM7M63" %}

Similar to the single SAC example, model Initialization is done using:

```
# Parse model specifications from the meta-parameters XML file
simulation_parameters = SimulationParameters(
    "simulation_parameters/plexus_SAC_meta.xml",
    note = 'plexus_SAC') 

# Use the model specification to initiate a new simulation
simulation = Simulation(simulation_parameters)
```

Plot the modeled network morphology:

```
simulation.plot_morphologies()
```

Get the soma plot:

```
simulation.plot_morphologies(soma_plt = True)
```

The synapse distribution:

Note that BC-SAC synapses are colored in red and SAC-SAC are colored in yellow-green, indicating pre-post synaptic connections. 

Similar to a single SAC, you can plot the channel distribution. RSME will generate a plot for each SAC.
