ENACT: End-to-End Analysis and Cell Type Annotation for Visium High Definition (HD) Slides

Note

This is the official repo for ENACT. The manuscript can be accessed through BiorXiv.

Spatial transcriptomics (ST) enables the study of gene expression within its spatial context in histopathology samples. To date, a limiting factor has been the resolution of sequencing based ST products. The introduction of the Visium High Definition (HD) technology opens the door to cell resolution ST studies. However, challenges remain in the ability to accurately map transcripts to cells and in cell type assignment based on spot data.

ENACT is the first tissue-agnostic pipeline that integrates advanced cell segmentation with Visium HD transcriptomics data to infer cell types across whole tissue sections. Our pipeline incorporates novel bin-to-cell assignment methods, enhancing the accuracy of single-cell transcript estimates. Validated on diverse synthetic and real datasets, our approach demonstrates high effectiveness at predicting cell types and scalability, offering a robust solution for spatially resolved transcriptomics analysis.

This repository has the code for inferring cell types from the sub-cellular transcript counts provided by VisiumHD.

This can be achieved through the following steps:

Cell segmentation: segment high resolution image using NN-based image segmentation networks such as Stardist.
Bin-to-cell assignment: Obtain cell-wise transcript counts by aggregating the VisiumHD bins that are associated with each cell
Cell type inference: Use the cell-wise transcript counts to infer the cell labels/ phenotypes using methods used for single-cell RNA seq analysis (CellAsign or CellTypist or Sargent if installed) or novel approaches, and use comprehensive cell marker databases (Panglao or CellMarker can be used as reference).

Note

At this time, Sargent is currently not available in GitHub.

System Requirements

ENACT was tested with the following specifications:

Hardware Requirements: 32 CPU, 64GB RAM, 100 GB (harddisk and memory requirements may vary depending on whole slide image size; if the weight of the wsi is small the memory requirements can be significantly decreased)
Software: Python 3.9, (Optional) GPU (CUDA 11)

Install ENACT from Source

Step 1: Clone ENACT repository

git clone https://github.com/Sanofi-OneAI/oneai-dda-spatialtr-enact.git
cd oneai-dda-spatialtr-enact

Step 2: Setup Python environment

Start by defining the location and the name of the Conda environment in the Makefile:

ENV_DIR := /home/oneai/envs/   <---- Conda environment location
PY_ENV_NAME := enact_py_env    <---- Conda environment name

Next, run the following Make command to create a Conda environment with all of ENACT's dependencies

make setup_py_env

Install ENACT with Pip

ENACT can be installed from Pypi using:

pip install enact-SO

Input Files for ENACT

ENACT requires only three files, which can be obtained from SpaceRanger’s outputs for each experiment:

Whole resolution tissue image. This will be segmented to obtain the cell boundaries that will be used to aggregate the transcript counts.
tissue_positions.parquet. This is the file that specifies the 2um Visium HD bin locations relative to the full resolution image.
filtered_feature_bc_matrix.h5. This is the .h5 file with the 2um Visium HD bin counts.

Defining ENACT Configurations

ENACT users can choose to specify the configurations via one of two ways:

Passing them within the class constructor:

  from enact.pipeline import ENACT

  so_hd = ENACT(
      cache_dir="/home/oneai/test_cache",
      wsi_path="Visium_HD_Human_Colon_Cancer_tissue_image.btf",
      visiumhd_h5_path="binned_outputs/square_002um/filtered_feature_bc_matrix.h5",
