sig-bio-shiny

An interactive application suite/interface for doing Exploration and Significant Biology on a set of Genes.

Note: Above is a screen recoding of SigBio-v0.2.1 (Few thing what you seeing in this recoding might be different when you download a recent version, as this project is going under rapid changes).

Try yourself?

Do it in your own computer system by following installation instructions or try one of the following methods.

For now this application requires atleast 4 GB of system memory. So couldn't able to host on shinyapps.io but instead with generous help of RStudio now this project Rstudio Cloud instance is 4GB. So you can simply login with following project link and follow run instructions.

Overview

The main motivation is to provide an easy interface to explore a Gene-set, without worrying about getting an organism database or conversion between particular R object which can be input to an available awesome R/Bioconductor package.

After downstream analysis of gene expression data, the end results are often a set of genes (may be a list of clustered genes, up/down regulated genes). To know their biological significance on a particular context (gene ontology or pathway) lot of statistical analysis available (Gene set enrichment, Over representation). Some awesome Bioconductor packages are developed for this purpose, But often the entry point might be difficult in some cases (mostly because of a particular input type). Also, besides that specifically for non-model organism it is little challenging.

Trying to solve these problems sig-bio-shiny is made. Completely made using R and Bioconductor. No manual database dump required, which make deployment simple with a single R Script. It takes full advantage of AnnotationHub package to get latest annotation for the selected organism and do statistical analysis on top of it using various well known packages.

Features

• Model and Non-model organism support with AnnotationHub
• Internal conversion of R objects for suitable input to a particular package/function/module.
• Modules
  • Gene mapping Annotation
  • Gene Ontology (GO) Enrichment
  • KEGG Pathway Enrichment

TODO

• Reproducible code (#25)
• Report generation
• Support for DESeq2 results object as input.

Installation

Requirements

R >= 3.5

From R console

if (!require(remotes)) { install.packages("remotes") }
  remotes::install_github("sk-sahu/sig-bio-shiny")

Run the app

Launch the app in browser.

SigBio::runApp()

Setup for Shiny-Server

First you need to install the SigBio package which have all the APIs required for most functionality in the shiny app.

Download the app.R file using wget from a specific app directory of your shiny-server.

wget https://raw.githubusercontent.com/sk-sahu/sig-bio-shiny/master/inst/app/app.R -O sig-bio-shiny-app.R

On the first time of running This will download and install all the required dependency.

With docker image

docker pull sudosk/sig-bio-shiny:latest
docker run --user shiny --rm -p 80:3838 sudosk/sig-bio-shiny:latest

Accessed app in a browser at http://127.0.0.1

Contribution

First of all thank you for your interest in contributing to this project :)

If you want to fix/report any bugs or add an extra module then please follow developer notes bellow. This will help us to maintain a specific structure to the project.

Developers Notes

Expand

Try to keep `app.R` file minimal, only with essential lines of code. For each module, Server and UI functions should specify in a single R script (Example: `module_modulename.R`) and additional required functions for that modules should be in another file (Example: `module_modulename_utils.R`)

I'll extend this section in more detail. Till then please feel free to contact for more details.

Whenever depolying to shinyapps.io - Ref

options(repos = BiocManager::repositories())
