Terminology Comparison: Legacy Scaffold and Scaffold 4

With the incorporation of protein clusters, we have modified and added new terms to capture different types of evidence, total and exclusive for example. These new terms particularly affect the display options in the Samples view that most Scaffold users are familiar with. Check the following definitions of the terms and table of correspondence with Scaffold 3.

New Terminology
Unique Peptides Peptides with different amino acids sequences, regardless of any modifications
Unique Spectra Spectra that differ in amino acid sequence, charge state or modification
Exclusive Associated with a single protein group
Total Associated with a protein group, whether it i shared with other protein groups
