Introduction

TCGAbiolinksGUI was created to help users more comfortable with graphical user interfaces (GUI) to search, download and analyze Cancer data. It offers a graphical user interface to the R/Bioconductor package TCGAbiolinks (Colaprico et al. 2016), which is able to access The National Cancer Institute (NCI) Genomic Data Commons (GDC) through its
GDC Application Programming Interface (API). Additional packages from Bioconductor are included, such as maftools (Mayakonda and Koeffler 2016) and ComplexHeatmap (Gu, Eils, and Schlesner 2016) packages to aid in visualizing the mutation data, ELMER (Yao et al. 2015) to identify regulatory enhancers using gene expression + DNA methylation data + motif analysis, Pathview (Luo and Brouwer 2013) for pathway-based data integration and visualization, and minfi for the processing of DNA methylation raw idat files.

The GUI was created using Shiny, a Web Application Framework for R, and uses several packages to provide advanced features that can enhance Shiny apps, such as shinyjs to add JavaScript actions for the app, shinydashboard to add dashboards and shinyFiles to provide an API for client side access to the server file system. A running version of the GUI is found in http://tcgabiolinks.fmrp.usp.br:3838/

This work has been supported by a grant from Henry Ford Hospital (H.N.) and by the São Paulo Research Foundation FAPESP (2016/01389-7 to T.C.S. & H.N. and 2015/07925-5 to H.N.) the BridgeIRIS project, funded by INNOVIRIS, Region de Bruxelles Capitale, Brussels, Belgium, and by GENomic profiling of Gastrointestinal Inflammatory-Sensitive CANcers (GENGISCAN), Belgian FNRS PDR (T100914F to A.C., C.O. & G.B.). T.C.S. and B.P.B. were supported by the NCI Informatics Technology for Cancer Research program, NIH/NCI grant 1U01CA184826.

Starting with TCGAbiolinksGUI

Installation

To install the package from the Bioconductor repository please use the following code.

source("https://bioconductor.org/biocLite.R")
biocLite("TCGAbiolinksGUI", dependencies = TRUE)

To install the development version of the package via GitHub:

source("https://bioconductor.org/biocLite.R")
devtools::install_github("BioinformaticsFMRP/TCGAbiolinksGUI.data",ref = "R_3.4")
devtools::install_github("BioinformaticsFMRP/TCGAbiolinksGUI")

Increasing loaded DLL

If you receive this error message: maximal number of DLLs reached... You will need to increase the maximum number of DLL R can load wit the enriroment variable R_MAX_NUM_DLLS.

For MACOS please modify the file /Library/Frameworks/R.framework/Resources/etc/Renviron and add R_MAX_NUM_DLLS=150 in the end. Or you can run in R the following command as R administrator: system(' echo "R_MAX_NUM_DLLS=150" >> /Library/Frameworks/R.framework/Resources/etc/Renviron')

For UBUNTU please modify the file /usr/lib/R/etc/Renviron and add R_MAX_NUM_DLLS=150 in the end. Or you can run in R the following command as R administrator: system(' echo "R_MAX_NUM_DLLS=150" >> /usr/lib/R/etc/Renviron')

For other OS check https://stat.ethz.ch/R-manual/R-patched/library/base/html/Startup.html.

Docker image

TCGAbiolinksGUI is available as Docker image (self-contained environments that contain everything needed to run the software), which can be easily run on Mac OS, Windows and Linux systems.

The image can be obtained from Docker Hub: https://hub.docker.com/r/tiagochst/tcgabiolinksgui/

For more information please check: https://docs.docker.com/ and https://www.bioconductor.org/help/docker/

Setting up image using graphical user interface (GUI)

This PDF shows how to install and execute the image using kitematic, which offers a graphical user interface (GUI) to control your app containers.

Setting up image using command-line

Download image: docker pull tiagochst/tcgabiolinksgui
To run RStudio Server and shiny-server, but the data is not saved if the container is stopped: sudo docker run --name tcgabiolinksgui -d -P -v /home/$USER/docker:/home/rstudio -p 3333:8787 -p 3334:3838 tiagochst/tcgabiolinksgui

For more information how data can be saved please read this wiki and see command below

To run RStudio Server, shiny-server and save the results in the host machine please use the code below: sudo docker run --name tcgabiolinksgui -d -P -v /home/$USER/docker:/home/rstudio -p 3333:8787 -p 3334:3838 tiagochst/tcgabiolinksgui

In case Rstudio is not accessible please check if the folder created (docker) has the right permission
If your system is windows or macOS you will need to change /home/$USER/docker to the correct system path. Examples can be found in this github page

To stop the image:

Run sudo docker stop tcgabiolinksgui to stop it

To start the image again (after the first time ran with docker run and stopped).

Run sudo docker start tcgabiolinksgui

Accessing the tools after the image is running:

TCGAbiolinksGUI will be available at :3334/tcgabiolinksgui
RStudio will be available at :3333 (username: rstudio , password:rstudio)

Quick start

The following commands should be used to start the graphical user interface.

library(TCGAbiolinksGUI)
TCGAbiolinksGUI()
