scFAIR: Single-Cell Genomics Data Standardization Initiative

Overview

scFAIR is an initiative to standardize single-cell genomics data and promote findable, accessible, interoperable, and reusable (FAIR) single-cell data. Our goal is to build a collaborative platform that supports and disseminates open research data (ORD) practices within the single-cell genomics community. This platform will enable researchers to upload, annotate, and access single-cell data and associated metadata, ensuring that these data are useful to an increasing community of specialists and non-specialists.

Background

Single-cell genomics has emerged as a transformative field within molecular biology, revolutionizing our understanding of cellular heterogeneity and paving the way for unprecedented insights into complex biological systems. As the quantity and diversity of single-cell data rapidly increase, the lack of clear reporting standards has led to multiple non-compatible datasets, limiting reusability. This presents challenges in making these data useful to the broader scientific community.

Need for Standardization

To address these challenges, there is a critical need for:

A centralized, standardized repository where researchers can collaboratively upload, annotate, and access single-cell data and associated metadata.
Standardized methods for storing and annotating single-cell data, particularly regarding essential metadata. This includes:
- Protocols
- Normalization and pipeline characteristics
- Cell type classifications and the methods used to classify them
- Association between barcodes and annotations

Adopting systematic data-sharing practices and standards is integral to fostering transparency, reproducibility, and effective utilization of single-cell genomics data.

Objectives

Build a collaborative platform for sharing datasets and their metadata.
Standardize the way data are shared across datasets.
Promote communication and outreach to increase the relevance and implementation of these standards within the single-cell genomics community.

Getting Started

To set up the project, follow these steps:

Create a /data folder in the root directory of the project.
Download the composite metazoan ontology file from the following link: http://purl.obolibrary.org/obo/uberon/composite-metazoan.obo.
Place the downloaded file in the /data folder.

After setting up the /data folder and placing the ontology file, run the following Rake commands in sequence:

rake obo:parse[/data/composite-metazoan.obo]
rake obo:update_adjacency_lists
rake api_updates

These commands will parse the ontology file, update the adjacency lists, and finally, update the API.
