        Default Modifications
        The default modifications are basically the ones implemented in the OMSSA search engine. Note that all modifications are not 
        compatible with X!Tandem and can result in nonsense matches. For instance, X!Tandem does not support modification at specific 
        amino acids on peptide termini.

        User Modifications
        User modifications can be implemented very easily in SearchGUI. Note that user modifications will be available in other 
        instances of SearchGUI and PeptideShaker.
