novae 1.1.3

💫 Graph-based foundation model for spatial transcriptomics data

Novae is a deep learning model for spatial domain assignments of spatial transcriptomics data (at both single-cell or spot resolution). It works across multiple gene panels, tissues, and technologies. Novae offers several additional features, including: (i) native batch-effect correction, (ii) analysis of spatially variable genes and pathways, and (iii) architecture analysis of tissue slides.

Documentation

Check Novae's documentation to get started. It contains installation explanations, API details, and tutorials.

Overview

(a) Novae was trained on a large dataset, and is shared on Hugging Face Hub. (b) Illustration of the main tasks and properties of Novae. (c) Illustration of the method behind Novae (self-supervision on graphs, adapted from SwAV).

Installation

novae can be installed from PyPI on all OS, for any Python version >=3.12.

pip install novae

Usage

Here is a minimal usage example. For more details, refer to the documentation.

import novae

# compute cell neighbors
novae.spatial_neighbors(adata)

# load a pre-trained model
model = novae.Novae.from_pretrained("prism-oncology/novae-human-0")

# compute spatial domains
model.compute_representations(adata, zero_shot=True)
model.assign_domains(adata)
