This vignette summarizes the functionalities and options of MSstastTMTPTM and provides a workflow example.

MSstatsTMTPTM includes the following two functions for data visualization and statistical testing:

  1. Data visualization of PTM and global protein levels: dataProcessPlotsTMTPMT
  2. Group comparison on PTM/protein quantification data: groupComparisonTMTPTM

Installation

To install this package, start R (version “4.0”) and enter:

if (!requireNamespace("BiocManager", quietly = TRUE))
    install.packages("BiocManager")

BiocManager::install("MSstatsTMTPTM")

1. dataProcessPlotsTMTPTM()

To illustrate the quantitative data and quality control of MS runs, dataProcessPlotsTMT takes the quantitative data from MSstatsTMT converter functions as input and generate two types of figures in pdf files as output : 1. Profile plot (specify “ProfilePlot” in option type), to identify the potential sources of variation for each protein; 2. Quality control plot (specify “QCPlot” in option type), to evaluate the systematic bias between MS runs.

Arguments

Example

The raw dataset for both the PTM and Protein datasets are required for the plotting function. This can be the output of the MSstatsTMT converter functions: PDtoMSstatsTMTFormat, SpectroMinetoMSstatsTMTFormat, and OpenMStoMSstatsTMTFormat. Both the PTM and protein datasets must include the following columns: ProteinName, PeptideSequence, Charge, PSM, Mixture, TechRepMixture, Run, Channel, Condition, BioReplicate, and Intensity.

3. groupComparisonTMTPTM()

Tests for significant changes in PTM abundance adjusted for global protein abundance across conditions based on a family of linear mixed-effects models in TMT experiment. Experimental design of case-control study (patients are not repeatedly measured) is automatically determined based on proper statistical model.

Arguments

  1. Otherwise, users can specify the comparisons of interest. Based on the levels of conditions, specify 1 or -1 to the conditions of interests and 0 otherwise. The levels of conditions are sorted alphabetically.

Example

# test for all the possible pairs of conditions
model.results.pairwise <- groupComparisonTMTPTM(data.ptm=quant.msstats.ptm,
                                       data.protein=quant.msstats.protein)
