Converting Project Data
Vision provides utility to convert spectra from System II format (2 nm spacing) to XDS data format
(0.5 nm spacing). The conversion is done on all spectra in an active project. During the conversion
Vision gives an option to reset the existing quant equations. If this option is chosen, all calibration
constants are deleted, but the sample selection results remain intact.
In order to convert the spectra follow these steps:
• Enter Data Acquisition mode and open the project to be converted.
• Click on File/Project/Convert Data.
• Confirm the operation:
• If the project contains calibrations, you will have an option to reset the equations:
It is recommended to do so and re-develop calibrations; however in some cases user may want to
retain the old equation. In particular, equations developed on 2 nm (System II) data can be used to
prediction on XDS analyzers. In this case Vision will skip extra points and apply System II calibration
on XDS data correctly.
• After successful conversion Vision displays the confirmation message:
Converting Library Data
Vision provides utility to convert libraries from System II format (2 nm spacing) to XDS data format
(0.5 nm spacing). The conversion is done on the library and all spectra in projects linked to the library.
During the conversion Vision deletes all library methods (clustering, ID method, and qualification
methods. However, the sample selection results and library structure remain intact.
In order to convert library follow these steps:
