Masslynx Raw Directory Data Structure

Question

[Ei Adimi]

Data acquired from the mass spectrometer is saved into data files on the computer’s hard disk.

All files are acquired to the data directory of the current project

For example if the file name is specified as test2 then the data files are stored in the directory c:\MassLynx\currentproject\data\test2.raw If the data file contains 1 acquisition functions then the directory listing will be as follows:

_ANALOGS.DAT Data file for analog temperature  

_ANALOGS.INF 

_Header.txt Data file header information

_Funcs.inf Information on functions acquired

_history.inf Information on how data has been processed

_expment.inf Experimental record information.

_Func001.dat Data file for first function (one for each function)

_Func001.idx Data file index for first function

im working on a peak detect software and need to know these binary files structure(Data format) for processing DAC data or creating a fake masslynx data directory manually.

Creating a directory does not sound very difficult and I have no idea what "i need these binary files structure" means. Please improve the question or it will be closed.

Not sure what your question is, really, but here are a few comments. I doubt you will ever learn the exact content of such files: each MS vendor has its own binary closed format. They however do provide libraries for programmatic data access. This is what allowed the development of converters to open data formats: mzData, mzXML, mzML are the main ones. Have a look a proteowizard's msconvert for implementation details.

If you are working on software that deals with raw MS data, I would suggest using open formats and allow yourself to have access to data from multiple instrument.

If converting to mzXML is desirable for the problem (hard to tell from the question) http://tools.proteomecenter.org/wiki/index.php?title=Software:massWolf might be interesting to the OP

[Laurent]

I believe msconvert should be preferred to massWolf since the latter is not actively maintained any more.
