tabula-muris

The Tabula muris data was generated by the Chan Zuckerberg Biohub. For a detailed description of the project please refer to our publication Transcriptomic characterization of 20 organs and tissues from mouse at single cell resolution creates a Tabula Muris. The Tabula muris project is a a compendium of single cell transcriptomic data from the mouse containing nearly 100,000 cells from 20 organs and tissues. The data allow for direct and controlled comparison of gene expression in cell types shared between tissues, such as immune cells from distinct anatomical locations. The resource also enables contrasting two distinct technical approaches:

• microfluidic droplet-based 3'-end counting, which provides a survey of thousands of cells per organ at relatively low coverage.
• FACS-based full length transcript analysis, which provides higher sensitivity and coverage.

This rich collection of annotated cells will be a useful resource for:

• Defining gene expression in previously poorly-characterized cell populations.
• Validating findings in future targeted single-cell studies.
• Developing of methods for integrating datasets (eg between the FACS and droplet experiments), characterizing batch effects, and quantifying the variation of gene expression in many cell types between organs and animals.

Since late 2017, Tabula muris data have been made available to all users free of charge. AWS has made the data freely available on Amazon S3 so that anyone can download the resource to perform analysis and advance medical discovery without needing to worry about the cost of storing Tabula muris data or the time required to download it.

Installation - Python

To install the Python dependencies, create a tabula-muris-env environment by using the environment.yml file provided:

conda env create -f environment.yml

Activate the environment and install it to your Jupyter notebook with:

source activate tabula-muris-env
python -m ipykernel install --user --name tabula-muris-env --display-name "Python 3.6 (tabula-muris-env)"

Installation - R

Packages:

install.packages(c("here", "Seurat", "useful", "ontologyIndex", "tidyverse"))

Getting started

From "raw" gene-cell counts tables

If you want to start from the raw gene-cell counts tables, then first download the data from figshare. You can download manually from the links (FACS and Droplet) or run a script we've prepared:

bash 00_data_ingest/download_data.sh

This will download two zip files,droplet_raw_data.zip and facs_raw_data.zip and unzip them into the folder structure described below. Then you'll have two folders in 00_data_ingest (the location is important - everything here depends on the folder structure).

FACS

The FACS folder should look like this:

00_facs_raw_data
├── FACS
│   ├── Aorta-counts.csv
│   ├── Bladder-counts.csv
│   ├── Brain_Myeloid-counts.csv
│   ├── Brain_Non-Myeloid-counts.csv
│   ├── Diaphragm-counts.csv
│   ├── Fat-counts.csv
│   ├── Heart-counts.csv

│   ├── Tongue-counts.csv
│   └── Trachea-counts.csv
├── FACS.zip

Droplet

Now your droplet folders should look like this:

01_droplet_raw_data
├── annotations_droplet.csv
├── droplet
│   ├── Bladder-10X_P4_3
│   ├── Bladder-10X_P4_4

│   ├── Liver-10X_P4_2
│   ├── Liver-10X_P7_0

│   ├── Tongue-10X_P4_0
│   ├── Tongue-10X_P4_1
│   ├── Tongue-10X_P7_10
│   ├── Trachea-10X_P8_14
│   └── Trachea-10X_P8_15
├── droplet.zip
└── metadata_droplet.csv

All of the *-10X_* folders contain a barcodes.tsv, genes.tsv, and matrix.mtx file as output by cellranger from 10X genomics.

01_droplet_raw_data/droplet/Bladder-10X_P4_3
├── barcodes.tsv
├── genes.tsv
└── matrix.mtx

Folder Organization

• FACS = SmartSeq2 on FACS-sorted plates
• Microfluidic = 10x droplet-based unique molecular identifier (UMI)-barcoded transcripts and cells
