SCIMAP 0.22.1

Spatial Single-Cell Analysis Toolkit

Single-Cell Image Analysis Package

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.

Installation

We strongly recommend installing scimap in a fresh virtual environment.

# If you have conda installed
conda create --name scimap python=3.8
conda activate scimap

Install scimap directly into an activated virtual environment:

$ pip install scimap

After installation, the package can be imported as:

$ python
>>> import scimap as sm

Notice for Apple M1 users

Please note that multiple python packages have not yet extended support for M1 users. Below is a temporary solution to install scimap in Apple M1 machines. Please follow the instructions in the given order.

# create and load a new environment
conda create -y -n scimap -c andfoy python=3.9 pyqt
conda activate scimap

# if you do not have xcode please install it
xcode-select --install

# if you do not have homebrew please install it
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

# if you do not have cmake install it
brew install cmake

# install h5py
