Optimizing liquid chromatography coupled to mass spectrometry (LC–MS) methods presents a significant challenge. The ‘rawDiag’ package (Trachsel et al. 2018), accessible through rawDiag, streamlines method optimization by generating MS operator-specific diagnostic plots based on scan-level metadata. Tailored for use on the R shell or as a shiny application on the Orbitrap instrument PC, ‘rawDiag’ leverages rawrr (Kockmann and Panse 2021) for reading vendor proprietary instrument data. Developed, rigorously tested, and actively employed at the Functional Genomics Center Zurich ETHZ | UZH, ‘rawDiag’ stands as a robust solution in advancing LC–MS Orbitrap method optimization."

Over the past two decades, liquid chromatography coupled to mass spectrometry (LC–MS) has evolved into the method of choice in the field of proteomics. (Cox and Mann 2011; Mallick and Kuster 2010) During a typical LC–MS measurement, a complex mixture of analytes is separated by a liquid chromatography system coupled to a mass spectrometer (MS) through an ion source interface. This interface converts the analytes that elute from the chromatography system over time into a beam of ions. The MS records from this ion beam a series of mass spectra containing detailed information on the analyzed sample. (Savaryn, Toby, and Kelleher 2016) The resulting raw data consist of the mass spectra and their metadata, typically recorded in a vendor-specific binary format. During a measurement the mass spectrometer applies internal heuristics, which enables the instrument to adapt to sample properties, for example, sample complexity and amount of ions in near real time. Still, method parameters controlling these heuristics need to be set prior to the measurement. Optimal measurement results require a careful balancing of instrument parameters, but their complex interactions with each other make LC–MS method optimization a challenging task.
Here we present rawDiag, a platform-independent software tool implemented in the R language (Becker, Chambers, and Wilks 1988) that supports LC–MS operators during the process of empirical method optimization. Our work builds on the ideas of the discontinued software rawMeat (VAST Scientific). Our application is currently tailored toward spectral data acquired on Thermo Fisher Scientific instruments (raw format), with a particular focus on Orbitrap (Zubarev and Makarov 2013) mass analyzers (Exactive or Fusion instruments). These instruments are heavily used in the field of bottom-up proteomics (Aebersold and Mann 2003) to analyze complex peptide mixtures derived from enzymatic digests of proteomes.
rawDiag is meant to run after MS acquisition, optimally as an interactive R shiny application, and produces a series of diagnostic plots visualizing the impact of method parameter choices on the acquired data across injections. If static reports are required then pdf files can be generated using rmarkdown. In this vignette, we present the usage of our tool.
rawDiag gains advantages from being part of the Bioconductor ecosystem, such as its ability to utilize the rawrr package and potentially extend its functionality through interaction with the Spectra infrastructure, particularly with the MsBackendRawFileReader.
rawDiag proides a wrapper function readRaw
using the
rawrr methods raw::readIndex
, rawrr::readTrailer
,
and rawrr::readChromatogram
to read proprietary mass spectrometer generated
data by invoking third-party managed methods through a system2
text connection
.
The rawrr package provides the entire stack below,

Otherwise, to execute the precompiled code, the following Linux packages are sufficient:
sudo apt-get install mono-runtime libmono-system-data4.0-cil -y

An inherent problem of visualizing data is the fact that depending on the data at hand, specific visualizations lose their usefulness, e.g., overplotting in a scatter plot if too many data points are present. To address this problem, we implemented most of the plot functions in different versions inspired by the work of Cleveland (1993), Sarkar (2008), and Wickham (2009). The data can be displayed in trellis plot manner using the faceting functionality of ggplot2. Alternatively, overplotting using color coding or violin plots based on descriptive statistics values can be chosen, which allows the user to interactively change the appearance of the plots based on the situation at hand. For instance, a large number of files are best visualized by violin plots, giving the user an idea about the distribution of the data points. On the basis of this, a smaller subset of files can be selected and visualized with another technique.
The code snippet below applies all plot methods on the example data.

The appearance of each plot depends on the instrument, sample, and method used to acquire the data. Therefore, it is hard to say what each ideal plot should look like. In particular, in the example above, we use data generated on an Orbitrap Fusion Lumos, 14946b3efdbaa_3238.raw and Q Exactive HF Orbitrap, 14946b6b79226c_4590.raw instrument using data-independent acquisition (DIA) (Bruderer et al. 2017) and data-dependent acquisition (DDA) methods. For more information on the plot methods and its application, please read the package man pages and the application examples in the manuscript (Trachsel et al. 2018).
The package provides a simple interactive shiny-based graphical user interface for exploring Thermo Fisher Scientific raw data.
If you have a directory containing raw files, you can create a shiny application as follows:
rawfile |>
dirname() |>
rawDiag::buildRawDiagShinyApp() -> app
The shiny runApp function launches the app in our browser.
shiny::runApp(app)
By default, the application lets you choose the raw files in the provided directory and provides the visualizations of the raw data as output. The user can interactively change the by the rawDiag the package provided plot functions and arguments.
Additionally, the application provides PDF generation and download buttons. Optionally height and width can be changed in the user interface.
Of note, the rawDiag::rawDiagServer
module can be integrated into an existing
shinydashboard application, e.g., https://shiny-ms.fgcz.uzh.ch/fgczmsqc-dashboard/.
consider all raw files of your working directory, e.g., ~/Downloads
and load them.
