. Agilent OpenLAB Enterprise Content Manager (ECM):. Automated file indexing for powerful search capability. Scheduled storage of files gathered from any vendors instruments or network storage location. Scalable for enterprise data storage In addition, Add-on packages can be added to OpenLAB ECM to extend the functionality.
Jump to:,mzXML is an 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, 3.0, and 3.1.
3.1 is the current version. The offical XML Schema components for the format are available at. Related FormatsPlease 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. As of version 4.0, the TPP supports mzML through an interface between RAMP.

As someone who just received their chem BSc but has always done programming as a hobby I feel like its a really niche thing to have a crossover between people who know programming and use these instruments day to day as a scientist. You're probably going to have to figure out the structure of the files formats yourself as I really doubt there's anyone who both has access to these instruments and knows how to do this to be able to publish documentation on it, aside from Agilent's engineers obviously.
You might be able to see if anyone who authored the Agilent plugins for OpenChrom can help you. I have an Agilent file converter for MATLAB that can handle.MS and.CH files. Feel free to check out the source code for the binary offsets and parsing algorithms-The.CH files seem to only record the signal values, so you will need to interpolate a time vector. The min/max time values are int32 in early file versions, float32 in later versions.
Unpacking the signal data is also different with earlier versions and some detectors (i.e. File information is stored using pascal strings- a value specifying the number of characters is located at the beginning of the field.Let me know if you have any questions. Fair warning- nearly everything I know about these formats is from reverse engineering them, so I can't guarantee everything is 100% correct.
