mzXML is a open data format for storage and exchange of mass spectroscopy data, developed at the SPC/Institute for Systems Biology. mzXML provides a standard container for ms and ms/ms proteomics data and is the foundation of our proteomic pipelines. Raw, proprietary file formats from most vendors can be converted to the open mzXML format.

Patrick Pedrioli was the primary original author; please see the references below for the often-cited Nature Biotech publication.

Several versions of this format exist. Currently these are 1.0 (also called "msXML"), 2.0, 2.1 and 3.0. 2.1 is the most common version currently in use.

Converters: status and summary table

All known formats and their converters are summarized in the table below:

Converter Overview

The first step in processing ms or ms/ms data with SPC proteomics software is conversion of raw data to our open mzXML format.

direct vendor support

Bruker

Bruker directly supports the mzXML format, using their CompassXport program:

CompassXport is the recommended converter for Bruker (.baf) files. (And for historical reasons only, we provide a page on our own (SPC-created) retired open-source Bruker converter, mzBruker.) Also, see Additional Resources, below.

SPC/TPP supported proprietary formats

The TPP project supports a wide variety of mass-spec instrument formats. Currently, we provide software tools (converters) for the following vendor formats. Follow the links for more specific information for each converter:

Thermo/XCalibur

ReAdW: Thermo/XCalibur raw data (.RAW files) to mzXML converter

Analyst (ABI/MDS Sciex)

mzWiff: Analyst (ABI/MDS Sciex) software's raw data (.wiff files) to mzXML converter.

Waters Masslynx

massWolf: MassLynx (Waters) raw data (.raw directories) to mzXML converter

Agilent MassHunter

trapper: MassHunter (Agilent) raw data (.d directories) to mzXML converter

Other external converter projects

These projects are not supported by the SPC, but may be of use.

msConvert. Part of the ProteoWizard Library. Available from http://proteowizard.sourceforge.net. Supports RAW, mzML and mzXML as of 6/08.

SCIEX/ABI 4700/4800 MALDI TOFTOF

T2Extractor - SCIEX/ABI 4700/4800 MALDI TOFTOF Data to mzXML: Java application to convert data from a SCIEX/ABI 4000 series MALDI TOFTOF instruments into mzXML format. This application is provided courtesy of Phil Andrews lab at the University of Michigan. Please see this link: [1]

ABI Mariner, Voyager

PyMsXML - ABI Mariner, Voyager raw data to mzXML: python-based converter. (Also supports Analyst .wiff files, but we recommend our own mzWiff program for that purpose.) Please see this link: http://www.umiacs.umd.edu/~nedwards/research/PyMsXML.html

Viewing mzXML files

Pep3D

The Pep3D program, included with the TPP, produces a gel-like image, which is very useful for getting an overview of an entire run. It can also link to CID and peptide probability information.

Insilicos viewer

We also recommend the free InSilicos Viewer, which can display mzXML, mzData, and other formats.

Parsing mzXML data

RAMP

RAMP: C/C++ API, contained in TPP and basis for TPP tools. Also parses mzData.

JRAP: java API

Related Formats

Please note that while widely accepted in the proteomics community mzXML is format, not a standard. There are two other open ms/ms proteomic formats: mzData and mzML. mzData was the first attempt, created by the HUPO/PSI committee process. Many vendors wanted to wait until the format was finalized (a process which took two years); in the meantime, mzXML was developed to fill the need.

mzML is a new format released 6/2008 which aims to marry the best elements of mzXML and mzData, and represents a joint effort of the HUPO/PSI committee, SPC/ISB, instrument vendors, and other proteomics software groups. It is intended and expected that mzML will replace the use of mzXML and mzData. For more information, visit the mzML development page. As of version 4.0, the TPP supports mzML through an interface between RAMP and Proteowizard.
