# Installation

cellclass is part of the omero-screen monorepo workspace. It is installed automatically when you run `uv sync` from the repository root.

``` bash
git clone https://github.com/Helfrid/omero-screen.git
cd omero-screen
uv sync --dev
source .venv/bin/activate
```

The unified `cellclass` command provides all CellClass workflows; run `cellclass --help` to see its subcommands, or browse the generated [CLI reference](../reference/cli/index.md) for the full command tree. Existing `cellclass-*` entry points remain available as compatibility aliases during the migration.


# Weights & Biases

Training runs are logged to [Weights & Biases](https://wandb.ai). Set up your credentials once:

``` bash
wandb login
```

Visit <https://wandb.ai/authorize>, log in, and paste the API key when prompted. The key is saved to `~/.netrc` and persists across sessions and on the Artemis cluster. Verify the setup with:

``` bash
wandb status
```

By default, runs log to the **cellclass** project in your own W&B workspace -- no shared credentials needed. To collaborate with a team, pass `--entity <team>` to `cellclass train` (e.g. `--entity hocheggerlab`), then share the project via the W&B interface.
