# Cohorts

## Introduction to Cohorts

ICA Cohorts is a cohort analysis tool integrated with Illumina Connected Analytics (ICA). ICA Cohorts combines subject- and sample-level metadata, such as phenotypes, diseases, demographics, and biometrics, with molecular data stored in ICA to perform tertiary analyses on selected subsets of individuals.

## Overview Video

This video is an overview of Illumina Connnected Analytics. It walks through a Multi-Omics Cancer workflow that can be found here: [Oncology Walkthrough](https://help.ica.illumina.com/project/p-cohorts/cohorts-walkthrough-cancer)

### Features At-a-glance

* Intuitive UI for selecting subjects and samples to analyze and compare: deep phenotypical and clinical metadata, molecular features including germline, somatic, gene expression.
* Comprehensive, harmonized data model exposed to ICA Base and ICA Bench users for custom analyses.
* Run analyses in ICA Base and ICA Bench and upload final results back into Cohorts for visualization.
* Out-of-the-box statistical analyses including genetic burden tests, GWAS/PheWAS.
* Rich public data sets covering key disease areas to enrich private data analysis.
* Easy-to-use visualizations for gene prioritization and genetic variation inspection.
