sevenbridges-r is an R/Bioconductor package that provides an interface for the Seven Bridges Platform (US, EU, China), Cancer Genomics Cloud, Cavatica, and BioData Catalyst Powered by Seven Bridges public APIs.
The Seven Bridges Platform is a cloud-based environment for conducting bioinformatics analysis. It is a central hub for teams to store, analyze, and jointly interpret their bioinformatic data. The Platform co-locates analysis pipelines alongside the largest genomic datasets to optimize processing, allocating storage, and compute resources on demand.
The Cancer Genomics Cloud (CGC), powered by Seven Bridges, is also a cloud-based computation environment. It was built as one of three pilot systems funded by the National Cancer Institute to explore the paradigm of colocalizing massive genomics datasets, like The Cancer Genomics Atlas (TCGA), alongside secure and scalable computational resources to analyze them. The CGC makes more than a petabyte of multi-dimensional data available immediately to authorized researchers. You can add your data to analyze alongside TCGA using predefined analytical workflows or your own tools.
Cavatica, powered by Seven Bridges, is a data analysis and sharing platform designed to accelerate discovery in a scalable, cloud-based compute environment where data, results, and workflows are shared among the world's research community. Cavatica is built in collaboration with the Children Hospital of Philadelphia and it is focused on pediatric data.
First, check the version of R you are using with the following command (in R):
R.version.stringIf you are not running the latest release version of R, install or upgrade with these instructions. If you are using RStudio, restart RStudio after installing R. RStudio will detect the new installation.
This is recommended for most users as it is the most stable version.
You can install the package from the release branch on Bioconductor using BiocManager:
install.packages("BiocManager")
BiocManager::install("sevenbridges")If you are developing tools under the devel branch or use the development version of R and Bioconductor, install the package from the Bioconductor devel branch. You probably also want to install R-devel first by following the directions in "Using the 'Devel' Version of Bioconductor".
To install the sevenbridges package from the devel branch, use
install.packages("BiocManager")
BiocManager::install("sevenbridges", version = "devel")To try the latest features, please install the package directly from GitHub. We push to the Bioconductor branch (release and devel) regularly.
Installing the sevenbridges package from GitHub requires you have the devtools package. If you do not have devtools, install it from CRAN first.
install.packages("devtools")You may get an error for missing system dependecies such as curl and ssl. You probably need to do the following first in order to install devtools and to build vignettes since you need pandoc under Ubuntu.
apt-get update
apt-get install libcurl4-gnutls-dev libssl-dev pandoc pandoc-citeprocAfter devtools is installed, install the latest version of sevenbridges from GitHub:
install.packages("BiocManager")
devtools::install_github(
"sbg/sevenbridges-r",
repos = BiocManager::repositories(),
build_vignettes = TRUE, dependencies = TRUE
)If you have trouble with pandoc and do not want to install it, set build_vignettes = FALSE to avoid building the vignettes.
The sevenbridges package includes the following features:
Multiple authentication methods support.
- Direct authentication:
# Direct authentication
a <- Auth(token = "your_token", platform = "cgc")
# or use base url
a <- Auth(token = "your_token", url = "https://cgc-api.sbgenomics.com/v2")- Authentication via system environment variables:
sbg_set_env(token = "your_token", url = "https://cgc-api.sbgenomics.com/v2")
a <- Auth(from = "env")- Authentication via a user configuration file, collect and manage your credentials for multiple accounts across various Seven Bridges environments:
a <- Auth(from = "file", profile_name = "aws-us-username")Please check vignette("api", package = "sevenbridges") for technical details about all available authentication methods.
A complete API R client with a user-friendly, object-oriented API with printing and support operations for API requests relating to users, billing, projects, files, apps, and tasks. Short examples are also included, as shown below:
# Get a project by pattern-matching its name
p <- a$project("demo")
# Get a project by its id
p <- a$project(id = "username/demo")
# Delete files from a project
p$file("sample.tz")$delete()
# Upload fies from a folder to a project and include file metadata
p$upload("folder_path", metadata = list(platform = "Illumina"))A task monitoring hook which allows you to add a hook function to specific task statuses as you monitor a task. For example, you can opt to receive an email when the task is completed or specify to download all files produced by the task, as shown below:
setTaskHook("completed", function() {
tsk$download("~/Downloads")
})
tsk$monitor()Batch tasks by metadata and by item.
# Batch by item
(tsk <- p$task_add(
name = "RNA DE report new batch 2",
description = "RNA DE analysis report",
app = rna.app$id,
batch = batch(input = "bamfiles"),
inputs = list(
bamfiles = bamfiles.in,
design = design.in,
gtffile = gtf.in
)
))
# Batch by metadata. Note that input files must
# have relevant metadata fields specified.
(tsk <- p$task_add(
name = "RNA DE report new batch 3",
description = "RNA DE analysis report",
app = rna.app$id,
batch = batch(
input = "fastq",
c("metadata.sample_id", "metadata.library_id")
),
inputs = list(
bamfiles = bamfiles.in,
design = design.in,
gtffile = gtf.in
)
))Cross-platform support for Seven Bridges environments, such as Cancer Genomics Cloud or Seven Bridges Platform on either Amazon Web Services or Google Cloud Platform.
A Common Workflow Language (CWL) Tool interface to directly describe your tool in R, export it to JSON or YAML, or add it to your online project. This package defines a complete set of CWL object, so you can describe tools as follows:
fd <- fileDef(name = "runif.R", content = readr::read_file(fl))
rbx <- Tool(
id = "runif",
label = "runif",
hints = requirements(
docker(pull = "rocker/r-base"),
cpu(1), mem(2000)
),
requirements = requirements(fd),
baseCommand = "Rscript runif.R",
stdout = "output.txt",
inputs = list(
input(id = "number", type = "integer", position = 1),
input(id = "min", type = "float", position = 2),
input(id = "max", type = "float", position = 3)
),
outputs = output(id = "random", glob = "output.txt")
)
# Print CWL JSON
rbx$toJSON(pretty = TRUE)
# Print CWL YAML
rbx$toYAML()Utilities for Tool and Flow, for example
library("sevenbridges")
# convert a SBG CWL JSON file
t1 <- system.file("extdata/app", "tool_star.json", package = "sevenbridges")
# convert json file into a Tool object
t1 <- convert_app(t1)
# shows all input matrix
t1$input_matrix()We maintain 3 different sets of documentation: the sevenbridges-r GitHub repository (latest and most up-to-date), Bioconductor release channel, and Bioconductor development channel. Below, only the GitHub version is linked to provide the latest documentation. For the other versions, please visit Bioconductor Release version or Bioconductor Development version. The tutorials below are re-generated regularly as we update the package on GitHub.

In the tutorial for IDE container above, we built a Docker container locally from which we can launch RStudio and Shiny. To launch RStudio and Shiny Server with the Seven Bridges IDE Docker container, do the following:
docker run -d -p 8787:8787 -p 3838:3838 --name rstudio_shiny_server sevenbridges/sevenbridges-rTo mount a file system, you need to use --privileged with fuse.
docker run --privileged -d -p 8787:8787 -p 3838:3838 --name rstudio_shiny_server sevenbridges/sevenbridges-rCheck out the IP from Docker Machine if you are on a Mac OS.
docker-machine ip defaultIn your browser, you can see where the RStudio server is located from the path http://<url>:8787/. For example, if 192.168.99.100 is returned, visit http://192.168.99.100:8787/ for Rstudio.
For the Shiny server, each app__ is hosted at http://<url>:3838/users/<username of rstudio>/<app_dir> for the Shiny server. For example, an app called 01_hello owned by user rstudio (a default user) has the path http://<url>:3838/users/rstudio/01_hello/. To develop your Shiny apps as an Rstudio user, you can login your RStudio server and create a folder in your home folder called ~/ShinyApps. There, you can develop shiny apps in that folder. For example, you can create an app called 02_text at ~/ShinyApps/02_text/.
Log into your RStudio at http://<url>:8787. Then, try to copy an app to your home folder, as follows:
dir.create("~/ShinyApps")
file.copy(
"/usr/local/lib/R/site-library/shiny/examples/01_hello/",
"~/ShinyApps/",
recursive = TRUE
)If you are logged in as user rstudio, visit http://192.168.99.100:3838/rstudio/01_hello. You should be able to see the "hello" example.
Note: Generic Shiny apps can also be hosted at http://<url>:3838/ or, for a particular app, at http://<url>:3838/<app_dir>. Inside the Docker container, it's hosted under /srv/shiny-server/.
