# **IMPORTANT**
This version of MutSeqR is built for Bioconductor version Development
(v3.23) and R v4.6.0. This is the first Bioconductor release. If you
cannot install the Development version, or are using an older version of
R, please use the
[working_version](https://github.com/EHSRB-BSRSE-Bioinformatics/MutSeqR/tree/working_version)
branch on GitHub.
## Overview
MutSeqR is an open-source R package to analyze error-corrected
Next-Generation Sequencing (ECS) data, empowering users with flexibility
during exploratory analyses while ensuring compatibility across
technologies.

<em>1. Data Import: Imports mutation data into the R environment. Binds
data from multiple libraries into a single object. Joins sample and
target region metadata to the mutation data. Retrieves trinucleotide
context. 2. Data Processing: Calculates mutation frequencies for groups
of interest. Calculates frequencies and proportions of mutation
subtypes. Optional Variant filtering: eliminates putative germline
variants, removes variants outside of specified regions, quality
assurance filtering. 3. Statistical Analyses: Generalized linear
modeling. Benchmark Dose Modeling. COSMIC signature analysis. Spectra
comparison between groups. Unsupervised clustering based on mutation
spectra. 4. Visualization: Create figures to display mutation
frequencies and the proportions of mutation subtypes. Visualise
statistical results. Visualise mutation distribution across genomic
loci. View clonal expansion of mutations. 5. Output: Summary report
RMarkdown file will faciliatte the generation of results. Output
mutation data as VCF. Output sequences in FASTA format. Output spectra
data in SigProfiler format. Export results to Excel workbook. </em>

## Installation
To install this package, start R (version “4.6”) and enter:
``` r
if (!require("BiocManager", quietly = TRUE))
install.packages("BiocManager")
# The following initializes usage of Bioc devel
BiocManager::install(version='devel')
BiocManager::install("MutSeqR")
```
## Examples
Example data is loaded through BioConductor ExperimentHub data package.
``` r
BiocManager::install("ExperimentHub")
library(ExperimentHub)
# Create an index
eh <- ExperimentHub()
query(eh, "MutSeqRData")
```
Access example data through the index:
``` r
example_data <- eh[["EH9857"]]
```
