# Basic Concepts

> Understand the three pillars and how they fit together.

Everything revolves around three simple concepts in AutocleanEEG:

    %% Labels

    %% Add descriptions as sublabels
    B1["Workspace<br><span style='font-size:12px'>Stores tasks and outputs</span>"]
    C1["Task<br><span style='font-size:12px'>config and analysis to run (built-in/custom)</span>"]
    D1["Input<br><span style='font-size:12px'>EEG data location</span>"]
    E1["Process<br><span style='font-size:12px'>Run pipeline</span>"]
```

* Workspace: folder for your tasks and outputs
* Task: what analysis pipeline to run (built-in or custom)
* Input: a single EEG file or folder of EEG files

## Corresponding commands

Use these commands to interact with each pillar.

| Pillar    | Command                           | Purpose (concise)                |
| --------- | --------------------------------- | -------------------------------- |
| Workspace | `autocleaneeg-pipeline workspace` | Manage or inspect a workspace    |
| Task      | `autocleaneeg-pipeline task`      | Define, list, or run a task      |
| Input     | `autocleaneeg-pipeline input`     | Specify / validate EEG data path |
