1. Workflow
1.1 Raw Data Format
Note: We are actively developing dedicated converters for
MSstatsPTM. If you have data from a processing tool that
does not have a dedicated converter in MSstatsPTM please add a github
issue https://github.com/Vitek-Lab/MSstatsPTM/issues and we
will add the converter.
The first step is to load in the raw dataset for both the PTM and
Protein datasets. Each dataset can formatted using dedicated converters
in MSstatsPTM, such as
FragePipetoMSstatsPTMFormat. If there is not a dedicated
converter for your tool in MSstatsPTM, you can
alternatively leverage converters from base MSstats. If
using converters from MSstats note they will need to be run
both on the global protein and PTM datasets.
You might notice a FASTA file is also needed for some converters. This FASTA file can be obtained by querying Uniprot with all of the protein IDs present in your PTM dataset. The FASTA file is a necessary input because some tools (e.g. MaxQuant) do not report the specific amino acid that is modified relative to the whole protein sequence. Rather, they report the specific amino acid relative to the reported peptide. This distinction is important because modifications like phosphorylation, methylation, or acetylation often have specific roles depending on where they occur within the full-length protein. With the help of a FASTA file, MSstatsPTM can determine the specific amino acid that is modified in the context of the whole protein sequence.
Please note for the PTM dataset, both the protein and modification
site (or peptide), must be added into the ProteinName
column. This allows for the package to summarize to the peptide level,
and avoid the off chance there are matching peptides between proteins.
For an example of how this can be done please see the code below.
The output of the converter is a list with two formatted data.tables.
One each for the PTM and Protein datasets. If a global profiling run was
not performed, the Protein data.table will just be NULL
1.1.1 MaxQuant - MaxQtoMSstatsPTMFormat
MSstatsPTM includes a dedicated converter for MaxQuant
output. Experiments can be acquired with label-free or TMT labeling
methods. No matter the experiment, we recommend using the
evidence.txt file, and not a PTM specific file such as the
Phospho (STY).txt file. The
MaxQtoMSstatsPTMFormat converter includes a variety of
parameters. Examples for processing a TMT and LF dataset can be seen
below.

MSstatsPTM includes a dedicated converter for FragPipe
output. Experiments must be acquired with TMT labeling methods (a
label-free converter is currently in development).The input is the
msstats.csv and annotation files automatically generated by
FragPipe. FragPipe provides additional info on the localization of
modification sites, and the FragPipetoMSstatsPTMFormat
converter includes localization options that are not present in other
converters.

MSstatsPTM includes a dedicated converter for Proteome
Discoverer output. Experiments can be acquired with label-free or TMT
labeling methods. The input is the psm file and a custom
built annotation file. Proteome Discoverer provides additional info on
the localization of modification sites, and the
PDtoMSstatsPTMFormat converter includes localization
options that are not present in other converters.

MSstatsPTM includes a dedicated converter for Skyline
output. Experiments can be acquired with label-free labeling
methods.
1.1.6 Peak Studio - PStoMSstatsPTMFormat
MSstatsPTM includes a dedicated converter for Peak
Studio output. Experiments can be acquired with label-free labeling
methods.
1.1.6 Progenesis - ProgenesistoMSstatsPTMFormat
MSstatsPTM includes a dedicated converter for Progenesis
output. Experiments can be acquired with label-free labeling
methods.
1.1.7 Additional tools
If there is not a dedicated MSstatsPTM converter for a
processing tool, the existing converters in MSstats and
MSstatsTMT converters can be used as described below.
Note, in order to do this, it is critical that the ProteinName column be a combination of the Protein Name and modification site.
As an example, if you would like to analyze an experiment processed
with DIANN, you can leverage the DIANNtoMSstatsFormat in
MSstats. Given two datasets, named raw_ptm_df
and raw_protein_df, and an annotation file, we can process
the data as follows.
# Add site into ProteinName column
raw_ptm_df$ProteinName = paste(raw_ptm_df$ProteinName,
raw_ptm_df$Site, sep = "_")
# Run MSstats Converters
PTM_data = MSstats::DIANNtoMSstatsFormat(raw_ptm_df, annotation)
PROTEIN_data = MSstats::DIANNtoMSstatsFormat(raw_protein_df, annotation)
# Combine into one list
msstatsptm_input_data = list(PTM = PTM_data, PROTEIN = PROTEIN_data)The variable msstatsptm_input_data can now be used as
the input to the remainder of the MSstatsPTM processing
pipeline.
1.2 Summarization - dataSummarizationPTM
After loading in the input data, the next step is to use the
dataSummarizationPTM function. This provides the summarized
dataset needed to model the protein/PTM abundance. The function will
summarize the Protein dataset up to the protein level and will summarize
the PTM dataset up to the peptide level. There are multiple options for
normalization and missing value imputation. These options should be
reviewed in the package documentation.
MSstatsPTM.summary = dataSummarizationPTM(raw.input, verbose = FALSE,
use_log_file = FALSE, append = FALSE)

summarization information. Each PTM and Protein include a list of
data.tables: FeatureLevelData is a data.table of
reformatted input of dataSummarizationPTM, ProteinLevelData
is the run level summarization data.
1.2.1 QCPlot
Once summarized, MSstatsPTM provides multiple plots to analyze the experiment. Here we show the quality control boxplot. The first plot shows the modified data and the second plot shows the global protein dataset.
1.2.2 Profile Plot
Here we show a profile plot. Again the top plot shows the modified peptide, and the bottom shows the overall protein.

which.Protein = "Q9Y6C9",

1.3 Modeling - groupComparisonPTM
After summarization, the summarized datasets can be modeled using the
groupComparisonPTM function. This function will model the
PTM and Protein summarized datasets, and then adjust the PTM model for
changes in overall protein abundance. The output of the function is a
list containing these three models named: PTM.Model,
PROTEIN.Model, ADJUSTED.Model.

The models from the groupComparisonPTM function can be
used in the model visualization function,
groupComparisonPlotsPTM. Here we show Volcano Plots for the
models.
groupComparisonPlotsPTM(data = MSstatsPTM.model,
type = "VolcanoPlot",
FCcutoff= 2,
logBase.pvalue = 2,
address=FALSE)
1.3.2 Heatmap Plot
Here we show a Heatmap for the models.
1.4 Sample Size Calculation - designSampleSizePTM
Finally, sample size calculation can be performed using the output of
the model and the designSampleSizePTM
# Specify contrast matrix
sample_size = designSampleSizePTM(MSstatsPTM.model, c(2.0, 2.75), FDR = 0.05,
numSample = TRUE, power = 0.8)
