AB/SCIEX

AB/SCIEX

The following AB/SCIEX data types can be manually converted to open formats:

  • .wiff from Analyst software (QStar, QTrap instruments)
  • .t2d from Data Explorer (4.2 and later) software (4x00 and 5x00 series TOF/TOF instruments)
  • .dat from Data Explorer (before 4.2) software (AB SCIEX Voyager (MALDI-TOF))

.wiff files conversion to mzXML or mzData

There are two different ways to convert .wiff files to open formats:

  1. Converting .wiff files to mzXML using mzWiff. mzWiff is a command-line program, which can be downloaded from the Sashimi project SourceForge, free of charge. mzWiff is also a part of the Trans-Proteomic Pipeline (TPP). Application requires the Analyst library from ABI/MDS Sciex to work properly, therefore the Analyst software has to be installed on a computer on which the conversion will be performed. Since the Analyst software is Windows platform dependent mzWiff works only under Windows. mzWiff replaces, improves and corrects mzStar software.
  2. Converting .wiff files to mzXML or mzData using CCwiffer. CCWiffer stands for the "Charleston Core Wiff Converter". The software converts .wiff files to the xml based formats: mzXML or mzData. Application requires the Analyst library from ABI/MDS Sciex to work properly, therefore the Analyst software has to be installed on a computer on which the conversion will be performed. Since the Analyst software is Windows platform dependent CCwiffer works only under Windows. Software can be downloaded from its SourceForge. The user manual shows in details how the conversion should be performed.

.dat files conversion to .txt files

ASCII Spectrum and ASCII Chromatogram (.txt) data can be extracted from the .dat files using AB/SCIEX Data Explorer software. To convert an entire data file to an ASCII text file:

  1. Open the data file you want to convert in Data Explorer.
  2. From the File menu, select Convert, then select ASCII text. Save As dialog box is displayed.
  3. Specify the name and destination for the file to be exported. By default, the software assigns a .txt extension to the file.
  4. Click OK.

The more detailed information can be found in the Data Explorer 4.0 User Guide.
