maftools - An R package to summarize, analyze and visualize MAF files
Introduction
maftools provides a comprehensive set of functions for processing MAF files and to perform most commonly used analyses in cancer genomics. See here for a detailed usage and a case study.
Installation
#Install from Bioconductor repository
BiocManager::install("maftools")
#Install from GitHub repository
BiocManager::install("PoisonAlien/maftools")
Getting started: Vignette and a case study
A complete documentation of maftools using TCGA LAML as a case study can be found here.
Besides the MAF files, maftools also facilitates processing of BAM files. Please refer to below vignettes and sections to learn more.
- Copy number analysis with ASCAT and mosdepth
- Generate personalized cancer report for known somatic hotspots
- Sample mismatch and relatedness analysis
