+**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.
+
+This tool runs a PCA dimensionality reduction
+
+-----
+
+**Inputs**
+
+    * Seurat RDS object, normalised and scaled potentially.
+    * Genes used to scale. File of gene names to scale/center. Default is all genes in object.
+    * Principal components to compute. Total Number of PCs to compute and store (20 by default). Less PCs might be faster, but will explain less variance.
+    * Use imputed. Boolean indicating whether to run PCA on imputed values or not.
+
+-----
+
+**Outputs**
+
+    * Seurat RDS object with PCA calculations and embeddings.
+    * Embeddings on CSV file. File with a csv-format embeddings table with principal components by cell.
+    * Loadings on CSV file. File with a csv-format loadings table with principal components by gene.
+    * Standard deviation on CSV file. Contains principal components std. deviations.
