# Variance-sensitive clustering of omics data
Feature-based variance-sensitive clustering of omics data. Optimizes cluster assignment by taking into account individual feature variance.
VSClust is available as interactive and user-friendly Shiny webservice and as R package in Bioconductor. For more instructions on both, see below.
VSClust was developed at the
[Protein Research Group](http://www.sdu.dk/en/Om_SDU/Institutter_centre/Bmb_biokemi_og_molekylaer_biologi/Forskning/Forskningsgrupper/Protein.aspx)

## Shiny app
### Web service
You can use the implementation on our web server http://computproteomics.bmb.sdu.dk:
http://computproteomics.bmb.sdu.dk/Apps/VSClust
Be aware that the tool does allow only one user to run the background R calculations at a time. Therefore the app might become temporarily irresponsive. However, multiple sessions are separated and your data won't be shared between sessions or overwritten.
### Local implementation
#### Docker
The easiest option is to use the docker image:
```
docker pull veitveit/vsclust
docker run -t -i -p 3838:3838 veitveit/vsclust
```
and access the server through http://localhost:3838
#### Bioconda
Install the package in the command-line
```
conda install -c bioconda vsclust
run_vsclust_app.sh
```
and access the shiny app through http://localhost:3838
#### Manual installation
Install the Bioconductor package `vsclust`
In R:
```
if (!require("BiocManager", quietly = TRUE))
install.packages("BiocManager")
BiocManager::install("vsclust")
```
You can run the shiny app from the server.R or ui.R files in the "inst/shiny" folder using [Rstudio](http://rstudio.com) or run the app on a [shiny-server](https://www.rstudio.com/products/shiny/shiny-server/)
Be aware that you need to have all files, the R libraries described in Installation *and* the modified e1071 library installed.
### Build and use Docker image
A Dockerfile has been created on top of the rocker/shiny docker image. Copy this repository to a folder and carry out the following command to build the image (takes a while)
`docker build -t veitveit/vsclust .`
You can also just directly download and run the image by
`docker run -t -i -p 3838:3838 veitveit/vsclust`
and access the server through http://localhost:3838
## Command line and R package
All operations but the gene set enrichment can be performed via command line running the R script `runVSClust.R`
or using the functions of the Bioconductor package `vsclust`
### Installation
#### In R:
```
if (!require("BiocManager", quietly = TRUE))
install.packages("BiocManager")
BiocManager::install("vsclust")
```
### As conda package
TBD
### Usage
Please take a look at the vignettes and/or in the help packages of the `vsclust` functions
