# Digital Twin Tabs

When you open a Digital Twin, you interact with it through a tabbed interface. Each tab serves a specific purpose in the model lifecycle.

***

### Overview Tabs

[**Home Tab**](https://docs.rootcause.ai/user-guide/digital-twin/tabs/home-tab)

Your command center. View twin metadata, select versions, and access quick actions for common tasks.

[**Config Tab**](https://docs.rootcause.ai/user-guide/digital-twin/tabs/config-tab)

Configure what goes into your Digital Twin: data source, included fields, temporal dependencies, and known/blocked relationships.

***

### Analysis Tabs

[**Relationships Tab**](https://docs.rootcause.ai/user-guide/digital-twin/tabs/relationships-tab)

View all discovered causal relationships. Edit the graph, resolve ambiguous directions, add or remove edges.

[**Path Analysis Tab**](https://docs.rootcause.ai/user-guide/digital-twin/tabs/path-analysis-tab)

Visualize causal flow with Sankey diagrams. See how influence propagates through your model.

[**Evaluation Tab**](https://docs.rootcause.ai/user-guide/digital-twin/tabs/evaluation-tab)

Assess model quality. View accuracy, MSE, R², and other metrics at both global and node levels.

***

### Simulation Tabs

[**Simulation Tab**](https://docs.rootcause.ai/user-guide/digital-twin/tabs/simulation-tab)

Run simulations: interventions, optimizations, counterfactuals, explanations, predictions, and forecasts.

***

### Version Management

[**Comparison Tab**](https://docs.rootcause.ai/user-guide/digital-twin/tabs/comparison-tab)

Compare different versions of your Digital Twin. See what changed in the causal graph between iterations.
