## Description
The package provides functions to filter, summarise and visualise
genetic variation data stored in VCF files.
Functionalities are also demonstrated in a Shiny web-application.
## Motivation
The VCF file format encodes a plethora of useful information,
including optional predictions using the
[Ensembl Variant Effect Predictor (VEP)](http://www.ensembl.org/info/docs/tools/vep/index.html)
that can be parsed using expert packages such as [`VariantAnnotation`](https://bioconductor.org/packages/release/bioc/html/VariantAnnotation.html)
and formatted into `VCF` objects.
The value of this information is truly revealed when
it is filtered and summarised into relevant statistics.
This package offers methods:
* to subset and summarise `VCF` objects including Ensembl VEP predictions,
* to explore genetic variants,
* and to report various summary statistics.
## Installation
Instructions to install the latest release of TVTB are available at:
http://bioconductor.org/packages/release/bioc/html/TVTB.html
Using `devtools`, versions more recent than the official releases can be
obtained:
install.packages("devtools")
The latest version pushed to Bioconductor
[release](https://github.com/Bioconductor-mirror/TVTB/tree/release-3.4)
(_may be more recent than the official release in the absence of version bump_)
:
devtools::install_github("Bioconductor-mirror/TVTB", ref="release-3.4")
The latest version pushed to Bioconductor
[devel](https://github.com/Bioconductor-mirror/TVTB/tree/master)
(_as above_):
devtools::install_github("Bioconductor-mirror/TVTB", ref="master")
Original [GitHub](https://github.com/kevinrue/TVTB/tree/master)
development repository:
devtools::install_github("kevinrue/TVTB")
Specific commit:
devtools::install_github("kevinrue/TVTB", ref="99966dda")
## Graphical User Interface
Although nothing offers more flexibility than the command line interface,
a [Shiny](http://shiny.rstudio.com/) web-application,
_the Shiny Variant Explorer_ (tSVE), offers a GUI
to get familiar with the major functionalities of the package.
## Tests
Unit tests and coverage implemented using the `testthat` package (CRAN).
Coverage excludes files:
* AllClasses.R (_Not executed at runtime_)
* tSVE.R (_Requires interactive session_)
