# Installation

## Installing nenucal

```
pip install nenucal-cd
```

This installs the following command-line tools:

| Command | Purpose |
|---|---|
| `nenudata` | NenuFAR data management, retrieval, and transfer |
| `calpipe` | Run the calibration pipeline |
| `modeltool` | Sky model building, filtering, clustering, inspection |
| `soltool` | Inspect and smooth gain solutions |
| `flagtool` | Manage FLAG column; run SSINS flagger |
| `mstool` | Measurement Set utilities |
| `imgpipe` | Imaging with WSClean |

## Requirements

nenucal requires Python ≥ 3.10.  Some functionality also relies on external
tools that must be installed separately:

- **DP3** — calibration and visibility processing — [dp3.readthedocs.io](https://dp3.readthedocs.io)
- **AOFlagger** — RFI flagging — [aoflagger.readthedocs.io](https://aoflagger.readthedocs.io)
- **WSClean** — imaging, used by `imgpipe` — [wsclean.readthedocs.io](https://wsclean.readthedocs.io)

> **Note:** `losoto` installs the legacy `progressbar` package while nenucal
> requires `progressbar2`. They share the same import name, so depending on the
> installation order you may need to force `progressbar2` back:
>
> ```bash
> pip uninstall progressbar && pip install --force-reinstall progressbar2
> ```
