Workflow
1. Preprocessing
1.1 Raw Data Format
The first step is to load in the raw dataset for both the PTM and Protein datasets. This data can then be converted into MSstatsLiP format with one of the built in converters, or manually converted. In this case we use the converter for Spectronaut.

## Make conditions match
MSstatsLiP_data[["LiP"]][MSstatsLiP_data[["LiP"]]$Condition == "Control",
"Condition"] = "Ctrl"
MSstatsLiP_data[["TrP"]]$Condition = substr(MSstatsLiP_data[["TrP"]]$Condition,
1, nchar(MSstatsLiP_data[["TrP"]]$Condition)-1)In the case above the SpectronauttoMSstatsLiPFormat was ran to convert the data into the format required for MSstatsLiP. Note that the condition names did not match between the LiP and TrP datasets. Here we edit the conditions in each dataset to match.
Additionally, it is important that the column “FULL_PEPTIDE” in the LiP dataset contains both the Protein and Peptide information, seperated by an underscore. This allows us to summarize up to the peptide level, while keeping important information about which protein the peptide corresponds to.
2. Summarization
The next step in the MSstatsLiP workflow is to summarize feature intensities per run into one value using the dataSummarizationLiP function. This function takes as input the formatted data from the converter.

2.2 Tryptic barplot
MSstatsLiP has a wide variety of plotting functionality to analysis and assess the results of experiments. Here we plot the number of half vs fully tryptic peptides per replicate.
trypticHistogramLiP(MSstatsLiP_Summarized,
"../inst/extdata/ExampleFastaFile.fasta",
color_scale = "bright",
address = FALSE)
2.3 Run Correlation Plot
MSstatsLiP also provides a function to plot run correlation.
2.4 Coefficient of Variation
Here we provide a simple script to examine the coefficient of variance between conditions
MSstatsLiP_Summarized[["LiP"]]$FeatureLevelData %>%
group_by(FEATURE, GROUP) %>%
summarize(cv = sd(INTENSITY) / mean(INTENSITY)) %>%
ggplot() + geom_violin(aes(x = GROUP, y = cv, fill = GROUP)) +
labs(title = "Coefficient of Variation between Condtions",
y = "Coefficient of Variation", x = "Conditon")
#> `summarise()` has grouped output by 'FEATURE'. You can override using the
#> `.groups` argument.
#> Warning: Removed 30 rows containing non-finite outside the scale range
#> (`stat_ydensity()`).
2.5 QCPlot
The following plots are used to view the summarized data and check for potential systemic issues.
## Quality Control Plot
dataProcessPlotsLiP(MSstatsLiP_Summarized,
type = 'QCPLOT',
which.Peptide = "allonly",
address = FALSE)
#> Drew the Quality Contol plot(boxplot) for all ptms/proteins.
2.6 Profile Plot
dataProcessPlotsLiP(MSstatsLiP_Summarized,
type = 'ProfilePlot',
which.Peptide = c("P14164_ILQNDLK"),
address = FALSE)
#> Drew the Profile plot for P14164_ILQNDLK (1 of 1)
#> Drew the Profile plot for P14164_ILQNDLK ( 1 of 1 )
2.7 PCA Plot
In addition, Priciple Component Analysis can also be done on the summarized dataset. Three different PCA plots can be created one each for: Percent of explained variance per component, PC1 vs PC2 for peptides, and PC1 vs PC2 for conditions.
PCAPlotLiP(MSstatsLiP_Summarized,
bar.plot = FALSE,
protein.pca = FALSE,
comparison.pca = TRUE,
which.comparison = c("Ctrl", "Osmo"),
address=FALSE)
PCAPlotLiP(MSstatsLiP_Summarized,
bar.plot = FALSE,
protein.pca = TRUE,
comparison.pca = FALSE,
which.pep = c("P14164_ILQNDLK", "P17891_ALQLINQDDADIIGGRDR"),
address=FALSE)
2.8 Calculate Trypticity
Finally, the trypticity of a peptide can also be calculated and added to any dataframe with the ProteinName and PeptideSequence column.
feature_data <- data.table::copy(MSstatsLiP_Summarized$LiP$FeatureLevelData)
data.table::setnames(feature_data, c("PEPTIDE", "PROTEIN"),
c("PeptideSequence", "ProteinName"))
feature_data$PeptideSequence <- substr(feature_data$PeptideSequence, 1,
nchar(as.character(
feature_data$PeptideSequence)) - 2)

3.4 Barcode
Here we show a barcode plot, showing the coverage of LiP and TrP peptides. This function requires the data in MSstatsLiP format and the path to a fasta file.

3.5 Calculate proteolytic resistance ratios
Proteolytic resistance ratios are calculated as the ratio of the intensity of fully tryptic peptides in the LiP condition to the TrP condition. In general, a low protease resistance value is indicative of high extent of cleavage, while high protease resistance values indicate low cleavage extent.
