With the rapid generation of high throughput datasets, the need for quick and reproducible data analysis tools has become paramount. Thus we developed DRPPM-EASY, an Expression Analysis App hosted in R ShinY. The application minimizes the need for extensive computational experience, providing an easy plug-and-play process to allow the user to explore their expression data on a web-based platform. The application provides many of the typical exploratory analyses and visualization, such as unsupervised hierarchical clustering, Gene Set Enrichment (GSEA), and differential gene expression. Results can be downloaded as a comprehensive table or gmt gene set for further downstream analysis.
The user can access the easy app through https://shawlab-moffitt.shinyapps.io/drppm_easy_url_app/
- Users may download a zip file of the GitHub repository or cloan it to their local workspace using the command line.
- Please check to make sure all of the pacakge dependencies are installed.
- As long as file structure and naming isn't effected, the app can be ran without any additional coding and files cant be input from the interface.
- Under the
User Data Inputsection of the app in the first section of the app.R script, users may include startup files and parameters and the app will upload the data when starting up. - If this app will be hosted on a server accessible to others, we have included a feature where you may specify a password in the script.
- This password is not acsessible from the interface, only the app.R script.

- Expression Matrix:
- A tab or comma delimited table with gene symbols or other features located in the first column with subsequent columns consiting of the sample name as the header and expression data down the column.
- The current App expects lowly expressed genes filtered out and normalized data either to FPKM or TMM.
- Larger files might inflict memory issues.
- Example
- Meta Data:
- A tab or comma delimited with two or more columns. First column consisting of sample names and following columns to be any additional meta or clinical data defining the sample.
- Example
- GeneSets:
- This folder contains currated gene sets from public recourses such as MSigDB, LINCS L1000, Cell Marker, as well as gene sets annotated in our lab defining immune signatures and ER stress signatures.
