The Spectrum Exporter node converts the spectrum from the available input formats, such as RAW and MGF files, to MGF, MZDATA, or MZML output files for processing elsewhere.

When you use the Spectrum Exporter with the Spectrum Selector node, the Spectrum Grouper node, or both, you can use the results with additional or customized data processing that is required outside of the application.

The following table describes the parameters for the Spectrum Exporter node.

Spectrum Exporter node parameters

Parameter

Definition

File Name

Specifies the name of the output file that contains the exported data.

File Name Suffix

Appends a suffix to the output file name. When you use multiple export nodes in a workflow—for example, to export HCD and ETD spectra—you can use the suffix to distinguish the contents of each output file.

Export Format

Specifies the format of the exported spectra:

  • Mascot Generic Format (MGF) (*.mgf): Places the exported spectra into MGF files, which are mass spectral files produced during Mascot analysis. They contain a list of precursor ions, their fragments, and the masses of the fragments.
  • MZDATA (*.mzData): Places the exported spectra into MZDATA files. The files are exported with XML indentation enabled so that the different XML tags are broken into multiple lines instead of merged into one line.
  • MZML (*.mzML): Places the exported spectra into MZML files, which are a combination of MZDATA and MZXML formats. The application supports version 1.1.0 of the MZML format. The MZML file also includes the version of the application that generated the MZML file.
