spectrum, use neutral loss window


The parameter can have the values yes or no.


  1. No error message is generated when an uninterpretable value is entered for this parameter.
  2. A default value of no is substituted if the parameter cannot be interpreted or is absent.


Some types of post-translational or chemical modifications can produce intense peaks in a spectrum because of a favoured fragmentation mechanism produced by the loss of a stable neutral molecule. These "neutral loss" peaks can be removed from a spectrum by setting appropriate values for the spectrum, neutral loss window and spectrum, neutral loss mass parameters (see the links below).
