Zebrahub-Multiome: a time-resolved single-cell multi-omic (RNA+ATAC) sequencing atlas of zebrafish development

Summary

This repo contains scripts (Python/R) and Jupyter notebooks used for processing and analyzing single-cell Multiome datasets from early zebrafish embryos. The manuscript is published here: Data is accessible through the Zebrahub portal: https://zebrahub.ds.czbiohub.org/

figures/

This directory contains various plots to make the main and supplementary figures. Note that the figures/ directory saves the output from the Jupyter notebooks or scripts from notebooks/, or scripts/ directories.

notebooks/

This directory includes a series of Jupyter notebooks that were used to create each figure or figure panel. We provide a structured tree diagram (below) representing the organization of the notebooks directory. This diagram delineates the specific notebooks responsible for generating each panel of the figures.

scripts/

These are R/Python modules that contain the bulk of the code used for data processing. Please note that these scripts are explicitly written for, and specific to this project and/or the Zebrahub-Multiome project. They are not intended to form a stand-alone or general-purpose Python package.

/environments: Setting up the conda environments

We used three conda environments listed below.

    1. single-cell-base: basic scanpy, numpy, pandas environment for Figure 1
    1. seacells: environment with SEACells for Figure 2 (see SEACells for troubleshooting)
    1. celloracle_env: environment for Figures 3 and 4 (see CellOracle documentation for troubleshooting)
