# Workflows

> Composable analysis pipelines that process your data

Workflows are the analysis pipelines that Atomscale runs on your data. Each workflow processes raw instrument data through a sequence of steps to extract metrics, detect patterns, or produce derived outputs. They run automatically when data arrives and store their results for visualization, comparison, and export.

## Characterization Workflows

Each characterization method on the platform is a workflow. When you upload or stream data from an instrument, the corresponding characterization workflow runs automatically to extract metrics and features specific to that technique.

## Cross-Cutting Workflows

These workflows operate across characterization data to provide additional analysis.
