peakPantheR

Package for Peak Picking and ANnoTation of High resolution Experiments in R, implemented in R and Shiny

Overview

peakPantheR is an R/Bioconductor package that implements functions to detect, integrate and report pre-defined features in MS files (e.g. compounds, fragments, adducts, …). It is designed for:

• Real time feature detection and integration (see Real Time Annotation)
  • process multiple compounds in one file at a time
• Post-acquisition feature detection, integration and reporting (see Parallel Annotation)
  • process multiple compounds in multiple files in parallel, store results in a single object

peakPantheR can process LC/MS data files in NetCDF, mzML/mzXML and mzData format as data import is achieved using Bioconductor’s mzR package.

The reference versions of peakPantheR is available on the corresponding Bioconductor page (release or dev version).

Active development and issue tracking take place on the github page, while an overview of the package, vignettes and documentation are available on the supporting website.

Installation

To install peakPantheR:

install.packages("BiocManager")
BiocManager::install("peakPantheR")

To install the development version from GitHub:

BiocManager::install("phenomecentre/peakPantheR")

Usage

Both real time and parallel compound integration require a common set of information:

• Path(s) to netCDF / mzML MS file(s)
• An expected region of interest (RT / m/z window) for each compound.

Vignettes

An overview of the package and detailed information on usage are available in the following vignettes:

• Getting Started with peakPantheR
• Real Time Annotation
• Parallel Annotation
• Graphical user interface use

Examples

Besides the vignettes, more tutorials are available via github:
