InterCellar 
an R/Shiny app for interactive analysis and exploration of cell-cell communication based on single-cell transcriptomics data
Description
InterCellar allows researchers to interactively analyze the results of cell-cell communication from scRNA-seq data. Starting from pre-computed ligand-receptor interactions, InterCellar provides filtering options, annotations and multiple visualizations to explore clusters, genes and functions. Moreover, based on functional annotation from Gene Ontology and pathway databases, InterCellar implements data-driven analyses to investigate cell-cell communication in one or multiple conditions.
Every step of the analysis can be performed interactively, thus not requiring any programming skills. Moreover, InterCellar runs on your local machine, avoiding issues related to data privacy.

Installation
Bioconductor
InterCellar is distributed as aBioconductor package and requires R (version 4.1) and Bioconductor (version 3.14).
To install InterCellar package enter:
if (!requireNamespace("BiocManager", quietly = TRUE)) install.packages("BiocManager")
BiocManager::install("InterCellar")
Bioconda and Docker
Alternatively, InterCellar can be installed throughBioconda. We recommend installing InterCellar in a fresh environment, such as:
conda create --name=intercellar_env conda activate intercellar_env conda install bioconductor-intercellar
Once the installation is done, you can start R simply by
A third option would be to pull the docker container as indicatedhere. Seebioconductor-intercellar/tagsfor valid values for , then run:
docker pull quay.io/biocontainers/bioconductor-intercellar:
Lastly, you would need to run
docker run -td quay.io/biocontainers/bioconductor-intercellar: docker exec -it /bin/bash
R
Launching the app
Once InterCellar is successfully installed, it can be loaded inside R or Rstudio as follow:
In order to start the app, please run the following command:
InterCellar::run_app( reproducible = TRUE )
InterCellar should be opening in a browser. If this does not happen automatically, please open a browser and navigate to the address shown (for example, Listening on http://127.0.0.1:6134). The flagreproducible = TRUE ensures that your results will be reproducible across R sessions.
Troubleshooting
Bioconductor
It might happen that the installation through BiocManager fails due to missing packages, throwing a similar error:
ERROR: dependencies 'golem', 'ComplexHeatmap' are not available for package 'InterCellar'
One solution would be to install the missing packages independently, such as:
BiocManager::install("ComplexHeatmap") install.packages("golem")
And afterwards re-install InterCellar:
BiocManager::install("InterCellar")
Bioconda and Docker
For users that have installed InterCellar through Bioconda or Docker, running InterCellar::run_app() might fail due to this error:
Error in utils::browseURL(appUrl) : 'browser' must be a non-empty character string
Try this solution:
After starting R
options(browser="firefox")
and then as usual
InterCellar::run_app( reproducible = TRUE )
