Overview

cinaR is a single wrapper function for end-to-end computational analyses of bulk ATAC-seq (or RNA-seq) profiles. Starting from a consensus peak file, it outputs differentially accessible peaks, enrichment results, and provides users with various configurable visualization options. For more details, please see the preprint.

Installation

# CRAN mirror
install.packages("cinaR")

Development version

To get bug fix and use a feature from the development version:

# install.packages("devtools")
devtools::install_github("eonurk/cinaR")

Known Installation Issues

Sometimes bioconductor related packages may not be installed automatically.
Therefore, you may need to install them manually:

BiocManager::install(c("ChIPseeker", "DESeq2", "edgeR", "fgsea","GenomicRanges", "limma", "preprocessCore", "sva", "TxDb.Hsapiens.UCSC.hg38.knownGene", "TxDb.Hsapiens.UCSC.hg19.knownGene", "TxDb.Mmusculus.UCSC.mm10.knownGene"))

Usage

library(cinaR)
#> Checking for required Bioconductor packages...
#> All required Bioconductor packages are already installed.

# create contrast vector which will be compared.
contrasts<- c("B6", "B6", "B6", "B6", "B6", "NZO", "NZO", "NZO", "NZO", "NZO", "NZO", 
              "B6", "B6", "B6", "B6", "B6", "NZO", "NZO", "NZO", "NZO", "NZO", "NZO")

# If reference genome is not set hg38 will be used!
results <- cinaR(bed, contrasts, reference.genome = "mm10")
