**What it does**

Seurat_ is a toolkit for quality control, analysis, and exploration of single cell RNA sequencing data.
It is developed and maintained by the `Satija Lab`_ at NYGC. Seurat aims to enable users to identify and
interpret sources of heterogeneity from single cell transcriptomic measurements, and to integrate diverse
types of single cell data.

Seurat clustering use SNN method to determine different clusters in your dataset. In order to construct a
SNN graph, you must have perform a PCA before launch this tool (you can use Seurat dimensional reduction).
It will search k (30) nearest neighbors for each cells and link cells to each other if they shared the
same neighbors. You can modulate the resolution in order to get larger (resolution superior to 1) or smaller
(inferior to 1) clusters.
