Introduction

TCGAbiolinksGUI was created to help users without knowledge of programming to search, download and analyze TCGA data. This package offers a graphical user interface to the R/Bioconductor packages TCGAbiolinks and ELMER packages. Also, some other useful packages from Bioconductor, such as ComplexHeatmap package has been used for data visualization.

A running version of the GUI is found in http://tcgabiolinks.fmrp.usp.br:3838/

Installing TCGAbiolinksGUI

To install the package from Bioconductor devel repository, please, use the code below.

# for the moment it must be devel version of Bioconductor
if (!requireNamespace("BiocManager", quietly=TRUE))
    install.packages("BiocManager")
BiocManager::install("TCGAbiolinksGUI", dependencies = TRUE)

To install the package development version from Github, please, use the code below.

if (!requireNamespace("BiocManager", quietly=TRUE))
    install.packages("BiocManager")
deps <- c("devtools")
for(pkg in deps)  if (!pkg %in% installed.packages()) BiocManager::install(pkg, dependencies = TRUE)
devtools::install_github("tiagochst/ELMER.data")
devtools::install_github("BioinformaticsFMRP/TCGAbiolinksGUI.data",ref = "R_3.4")
devtools::install_github("BioinformaticsFMRP/TCGAbiolinksGUI")

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 container is stopped: sudo docker run --name tcgabiolinksgui -d -P -v /home/$USER/docker:/home/rstudio -p 3333:8787 -p 3334:3838 tiagochst/tcgabiolinksgui
1. For more information how data can be saved please read this wiki and see command below
To run RStudio Server, shiny-server and save the results in the host machine please use the code below: sudo docker run --name tcgabiolinksgui -d -P -v /home/$USER/docker:/home/rstudio -p 3333:8787 -p 3334:3838 tiagochst/tcgabiolinksgui
1. In case rstudio is not accessible please check if the folder created (docker) has the right permission
2. If your system is windows or mac 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:
1. Run sudo docker stop tcgabiolinksgui to stop it
To start the image again (after the first time ran with docker run and stopped).
1. Run sudo docker start tcgabiolinksgui

Accessing 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 in order to start the graphical user interface.

library(TCGAbiolinksGUI)
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. R_MAX_NUM_DLLS In MACOS just modify the file /Library/Frameworks/R.framework/Resources/etc/Renviron and add R_MAX_NUM_DLLS=110 in the end.

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