Parameter: fixed_modification_protC

Overview

Specifies a mass adjustment to be applied to all protein C-termini prior to spectral analysis. The relative mass difference may be any non-zero number.

NOTE: When the mass value of fixed_modification_protC is zero, the parameter is ignored. Some configuration files may have the value set to zero, simply to have a fixed_modification_protC placeholder in the file.
