What Is mzCloud?

1.Create a new Xcalibur method via the standard method editor. Enter LC settings, Tune ﬁles, etc. As you would normally do. Please refer to the Xcalibur user manual for help. Caution: Make sure that the MS method duration is equal to your LC run time. The Sashimi project hosts the Trans-Proteomic Pipeline (TPP), a mature suite of tools for mass-spec (MS, MS/MS) based proteomics: statistical SASHIMI - Browse /ReAdW (Xcalibur converter)/ReAdW-3.5.3 at SourceForge.net.

mzCloud represents a key conceptual shift towards a modern mass spectral database
A scientifically solid and computationally robust platform for the identification of small molecules using tandem mass spectrometry
It comprises curated databases of high and low resolution MSⁿ spectra acquired under a number of experimental conditions which address the spectra reproducibility problem
A freely searchable collection of spectra, spectral trees, structures, fragments, precursor ions, chromatographic data and compound related references
A web-based interface providing a number of search, visualization and data processing tools
A Cloud solution allowing registered users to create individual, public or private spectral libraries (in the future)
An open, collaborative effort of dedicated research and industrial partners aiming to establish a comprehensive library of high quality spectral trees

Where Could Traditional Methods Improve?

In peer reviewed journals, the identification bottleneck has been repeatedly solved, even in an automated manner. In reality, we observe 1,000s of components in a typical LC/MS run, but we only know the identities of 100s
Inherent problems with structure elucidation prohibit a fully automated identification of compounds
Identification cannot be solved simply by elaborate frameworks, protocols, formats ...
There is a growing concern about the true identity of compounds claimed to be positively identified, especially in multi-disciplinary fields where mass spectrometry is used as just a tool without a deep understanding of the fundamentals
Existing mass spectral databases contain virtually the same compounds
Low resolution scoring algorithms are often used for high resolution mass spectra
The scientific and industrial community is confronted with an avalanche of questionable 'modular' computational methods that ignore the basic mass spectrometric principles and which can hardly lead to correct results
An important fact often neglected is that identification is tightly coupled with instrumentation
Because of the immense structural diversity of small molecules, a single molecular formula may represent tens of thousands of possible chemically relevant structures, so a molecular formula estimate cannot be regarded as a compound identification nor as a peak annotation

What Makes mzCloud a Better Tool?

mzCloud tries to address the identification bottleneck by considering all mass spectrometrically relevant aspects, by looking at a number of experimental and computational details and, in some cases, allowing the identification of unknowns even if they are not present in the library. Please see the full list of mzCloud features.

Data independent acquisition (DIA) mass spectrometry is a powerful technique that is improving the reproducibility and throughput of proteomics studies. EncyclopeDIA is library search engine comprised of several algorithms for DIA data analysis and can search for peptides using either DDA-based spectrum libraries or DIA-based chromatogram libraries. Check out our manuscript describing EncyclopeDIA at Nature Communications (Searle et al, 2018) for more information. EncyclopeDIA contains Walnut, an implementation of the PECAN (Ting et al, 2017) scoring system, to enable chromatogram library generation from FASTA protein sequence databases when spectrum libraries are unavailable. EncyclopeDIA also supports Prosit, a deep learning tool for generating peptide fragmentation spectra, as described in our new methods paper (Searle et al, 2020).

How do I get EncyclopeDIA?

EncyclopeDIA is open source under the Apache 2 licence, which means you can do what you like with the software, as long as you include the required notices. You can download the latest stable version or look at the manual.

How do I start collecting DIA?

You can check out a DIA quick start document you're interested in how to set up your instrument to collect DIA data or check out recommended starting settings for DIA on Thermo instruments. Our new 'tutorial', Pino et al, 2020, is a great place to gain intuition about why these methods and settings make sense. This content is consolidated in our ASMS 2020 talk, which has full lecture notes and an accompanying video on YouTube.

How do I get or make libraries?

Walnut can be used for searching DIA files without a library. However, we recommend using libraries for maximum sensitivity. If you're doing work with Human samples (including tissue or cells), you can download an EncyclopeDIA-compatible version of the Pan-Human library created from the Rosenberger et al, 2014 dataset. Alternatively, if you're doing work with non-human samples, you can download a pre-generated Prosit library or read our tutorial on developing new Prosit libraries using only a FASTA database.

Finally, EncyclopeDIA is designed to enable the chromatogram library workflow. This DDA-free strategy builds sample-specific libraries using gas-phase fractionation (GPF) DIA. GPF-DIA improves detection rates by injecting the same sample six times, from 400-500 m/z, 500-600 m/z, etc. This allows each run to have PRM-quality DIA windows (2 m/z or less) with the same instrument duty cycle. While offline fractionation such as SCX or high-pH RP requires an additional liquid chromatography step, GPF occurs completely within the mass spectrometer, making very easy to perform. The 6x GPF-DIA files can be searched with Walnut or a Prosit-based library to produce sample-specific chromatogram libraries, which are in turn used to search normal (wide-window) DIA files.

How do I use EncyclopeDIA?

Xcalibur Mass Spectrometry Software Download Mac

EncyclopeDIA is a cross-platform Java application that has been tested for Windows, Macintosh, and Linux. Specifically, we have tested it under Windows 8 and 10, Mac OS X 10.11-15, and RedHat Linux 4.4. The EncyclopeDIA GUI can be opened by double clicking on the EncyclopeDIA .JAR (e.g. EncyclopeDIA-0.9.5-executable.jar). EncyclopeDIA can also be used at the command line and there are more detailed instructions for this available in the FAQs.

EncyclopeDIA requires 64-bit Java 1.8. If you don’t already have it, you can download either the “Windows x64 Offline”, 'Mac OS X x64 .DMG' or 'Linux x64' link from the Java SE Runtime Environment 8 downloads website, depending on your specific operating system. The download and installation time should take only a few minutes.
