## The Assay Class

### Description

The Assay object is the basic unit of Seurat; each Assay stores raw, normalized, and scaled data as well as cluster information, variable features, and any other assay-specific metadata. Assays should contain single cell expression data such as RNA-seq, protein, or imputed expression data.

### Slots

`counts`

  Unnormalized data such as raw counts or TPMs

`data`

  Normalized expression data

`scale.data`

  Scaled expression data

`key`

  Key for the Assay

`assay.orig`

  Original assay that this assay is based off of. Used to track assay provenance

`var.features`

  Vector of features exhibiting high variance across single cells

`meta.features`
