SpecDataPointEx

Remarks

Provides a means for storing extended spectral data point values. There are limited sources of these additional data. Notably, such extended information can be obtained when reading mass spectra from the Thermo Fisher Scientific native vendor format (raw). The extended information is only available if the spectra was acquired in a suitable analyzer (e.g., Orbitrap) and has been processed to centroid format. Use of SpecDataPointEx is not relevant for profile data or spectra where the extended information is not stored. In those cases, the extended properties will contain zero values.
