Parameter: fragment_bin_offset

Overview

An offset applied to the binning algorithm when scoring spectra. The offset facilitates centering observed peaks in the bin when using large bin sizes with low-resolution MS/MS spectra. For ion trap (low-res) MS/MS spectra, the recommended value is 0.4. An offset is not necessary, and potentially detrimental, for high-res MS/MS. For high-res MS/MS, the recommended value is 0.0.

Examples

To indicate an offset for high-resolution MS/MS spectra:

fragment_bin_offset = 0.0

To indicate an offset for low-resolution MS/MS spectra:

fragment_bin_offset = 0.4
