## **Introduction**
---
This is a web-based interactive application that wraps the popular <a href="https://bioconductor.org/packages/release/bioc/html/clusterProfiler.html" target="_blank"><strong>clusterProfiler</strong></a> package which implements methods to analyze and visualize functional profiles of genomic coordinates, gene and gene clusters.
Users can upload their own differential gene expression (DGE) data from <a href="https://bioconductor.org/packages/release/bioc/html/DESeq2.html" target="_blank"><strong>DESeq2</strong></a> or import data from the upstream <a href="http://nasqar.abudhabi.nyu.edu/deseq2shiny/" target="_blank"><strong>Deseq2Shiny</strong></a> app.
This app allows for quick and easy **Gene Set Enrichment Analysis (GSEA)** of GO-Terms and KEGG pathways.
It is meant to provide an intuitive interface for researchers to easily **upload and perform GSEA on RNA-seq data** interactively with no prior programming knowledge in R.
Visuals produced include dot plots, category net plots, enrichment map plots, GO induced graphs, gsea plots, and enriched KEGG pathway plots using the <a href="https://bioconductor.org/packages/release/bioc/html/pathview.html" target="_blank"><strong>Pathview package</strong></a>.
The application follows this <a href="https://learn.gencore.bio.nyu.edu/rna-seq-analysis/gene-set-enrichment-analysis/" target="_blank">tutorial</a> <link>
See **Figure 1** below for example output plots (Click on image to enlarge).

## **Input Data Types**
---
This application accepts the following types of input data:
### 1. Example data (Demo):
- For demo purposes, you can select "Example data"
- You can follow the steps afterwards to run the analysis mirroring the <a href="https://learn.gencore.bio.nyu.edu/rna-seq-analysis/over-representation-analysis/" target="_blank">tutorial</a> in order to get familiar with the app
### 2. Upload your own data (gene counts):
<div class="row">
<div class="col-md-6">
<ul>
<li><p>A .csv/.txt file that contains a <strong>table of differential gene expression (DGE) data</strong></p></li>
<li><p>Eg. the output of DESeq2 </p></li>
<li><p>The file can be either <strong>comma or tab delimited</strong></p></li>
<li><p>The required columns are <strong>Gene name/id, Log2 Fold Change, p-adjusted values </strong></p></li>
<li><p>You will have to select the column names that match the above required columns </strong></p></li>
<li><p>For a sample file, click <a href="www/exampleData/drosphila_example_de.csv" target="_blank">here</a></p></li>
</ul>
</div>
<div class="col-md-6">
<p><strong><em>Figure 2: Eg. DGE data file</em></strong></p>
<div class="BoxArea4" style="width: 100%;margin: 0 auto;display: block;">
