BiasCorrector is published in 'BiasCorrector: fast and accurate correction of all types of experimental biases in quantitative DNA methylation data derived by different technologies' (2021) in the International Journal of Cancer (DOI: https://onlinelibrary.wiley.com/doi/10.1002/ijc.33681).
BiasCorrector is the user friendly implementation of the algorithms described by Moskalev et. al in their research article 'Correction of PCR-bias in quantitative DNA methylation studies by means of cubic polynomial regression', published 2011 in Nucleic acids research, Oxford University Press (DOI: https://doi.org/10.1093/nar/gkr213).

Make sure, you have R installed on your system:
-
Then open your development environment and install this R package:
You can install BiasCorrector simply with via R's install.packages interface:
install.packages("BiasCorrector")If you want to use the latest development version, you can install the github version of BiasCorrector with:
install.packages("remotes")
remotes::install_github("kapsner/BiasCorrector")- To start BiasCorrector, just run the following command in R. A browser tab should open displaying BiasCorrector. Alternatively you can type the URL "localhost:3838/" in your browser.
library(BiasCorrector)
launch_app()To simplify installation an deployment of BiasCorrector you can clone this repository and build your own docker image. Make sure, you have Docker and docker-compose installed on your system.
# clone the repository
git clone https://github.com/kapsner/BiasCorrector
# go to the docker subfolder
cd BiasCorrector/docker/
# run the build script
./build_image.sh
# when the building is finished, just start the container by running
docker-compose -f docker-compose.local.yml up -d
# clone the repository
git clone https://github.com/kapsner/BiasCorrector
# go to the docker subfolder
cd BiasCorrector/docker/
# start the Docker container
docker-compose -f docker-compose.remote.yml up -d
Type the URL "localhost:3838/" in your browser and start working with BiasCorrector.
BiasCorrector depends on the rBiasCorrection R-package, which is the implementation of the core functionality to correct measurement biases in DNA methylation analyses. BiasCorrector brings this functionality to a user-friendly shiny web application.
rBiasCorrection is available at https://github.com/kapsner/rBiasCorrection.
A video tutorial describing the workflow of how to use BiasCorrector in order to correct measurement bias in DNA methylation data is available on youtube.
A demo version of BiasCorrector is available here.
More detailed information on how to use the backend-package rBiasCorrection can be found in its vignette. The FAQs can be found here.
