GALAssify

==========

A tool to manually classify galaxies.

We also provide a help tools to:

- Download images from SDSS.

- Create a instructions pdf.

The tool can be customized with the `config` file.

Installing

----------

Install and update using [pip](https://pip.pypa.io/en/stable/getting-started/):

```

$ pip install git+https://gloton.ugr.es/gitlab/lss/GALAssify.git

```

Should work with `python >= 3.9`. Feel free to try for lower versions.

Usage

-----

Using a virtual enviroment is recommended to execute this tool:

```bash

cd DIR_GALAssify

python -m venv .env

source .env/bin/activate

pip install -r requirements.txt

```

For the main tool check:

```python

python galassify.py --help

```

For helper tools check:

```python

python get_images_sdss.py --help

```
