RT Journal Article SR Electronic T1 scSVA: an interactive tool for big data visualization and exploration in single-cell omics JF bioRxiv FD Cold Spring Harbor Laboratory SP 512582 DO 10.1101/512582 A1 Marcin Tabaka A1 Joshua Gould A1 Aviv Regev YR 2019 UL http://biorxiv.org/content/early/2019/01/06/512582.abstract AB We present scSVA (single-cell Scalable Visualization and Analytics), a lightweight R package for interactive two- and three-dimensional visualization and exploration of massive single-cell omics data. Building in part of methods originally developed for astronomy datasets, scSVA is memory efficient for more than hundreds of millions of cells, can be run locally or in a cloud, and generates high-quality figures. In particular, we introduce a numerically efficient method for single-cell data embedding in 3D which combines an optimized implementation of diffusion maps with a 3D force-directed layout, enabling generation of 3D data visualizations at the scale of a million cells. To facilitate reproducible research, scSVA supports interactive analytics in a cloud with containerized tools. scSVA is available online at https://github.com/klarman-cell-observatory/scSVA.
