Spatial Single-Cell Analysis Toolkit
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 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.

We strongly recommend installing scimap in a fresh virtual environment.
# If you have conda installedconda create --name scimap python=3.10conda 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:
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:
pip install scimap
After installation, the package can be imported as:
$ python>>> import scimap as sm
scimap functions and tutorials are available here.Scimap development was led by Ajit Johnson Nirmal, Harvard Medical School.
