mzTab is meant to be a light-weight, tab-delimited file format for proteomics data. The target audience for this format are primarily researchers outside of proteomics. It should be easy to parse and only contain the minimal information required to evaluate the results of a proteomics experiment. One of the goals of this file format is that it, for example, should be possible for a biologist to open such a file in Excel and still be able to "see" the data. The aim of the format is to present the results of a proteomics experiment in a computationally accessible overview. The aim is not to provide the detailed evidence for these results, or allow recreating the process which led to the results. Both of these functions are established through links to more detailed representations in other formats, in particular mzIdentML and mzQuantML.

The spectra data related with the identifications in the mzTab files should be referenced from the mzTab files. Currently, PRIDE Inspector supports mzML, mzXML, pkl, mgf, ms2 and dta file formats. The reference to the original spectra must be added during the loading process of each mzTab file (More information). If you have problems with spectra referencing please contact the pride support team: PRIDE HelpDesk.
Please refer to PSI's online documentation if you want a detailed description on mzTab:
