*Scimap* is a scalable toolkit for analyzing spatial molecular data. The underlying framework is generalizable to spatial datasets mapped to XY coordinates. The package uses the [anndata](https://anndata.readthedocs.io/en/stable/anndata.AnnData.html) framework making it easy to integrate with other popular single-cell analysis toolkits. It includes preprocessing, phenotyping, visualization, clustering, spatial analysis and differential spatial testing. The Python-based implementation efficiently deals with large datasets of millions of cells.

## Installation

We strongly recommend installing `scimap` in a fresh virtual environment.

```
# If you have conda installed
conda create --name scimap python=3.10
conda activate scimap
```

Install `scimap` directly into an activated virtual environment:
  
**Firstly, we suggest installing `scimap` and `napari` together to enable visualization out of the box. Keep in mind, `napari` needs a GUI toolkit, such as PyQt. If you run into any issues because of your computer's operating system, install `scimap` and `napari` separately by following the guidance in `napari's` documentation.**

Here's how you can install both using pip:

```python
pip install "scimap[napari]"
```

**If you encounter a problem with PyQt6 during the installation, you can install `scimap` alone first. Later on, if you find you need `napari`, you can go ahead and install it by itself.**

To install just `scimap`:

```python
pip install scimap
```

After installation, the package can be imported as:

```python
$ python
>>> import scimap as sm
```

## Get Started
