+Peptide unicity in an hEIDI context is based on sequence & calculated mass.\\
+For example, the peptide ''FASFIDKVR'' is represented by one peptide node in the ''Peptide View''. \\
+This peptide matches on 15 master proteins (see the ''Protein Group(s) match(es)'' column) but 7 other proteins as well (information not visible in hEIDI)\\
+{{:userguide:pride_onepeptideinheidi.png|}}
+In Pride Inspector, a row exists for each peptide-protein match.\\
+For example, the peptide ''FASFIDKVR'' appears 22 times: one row for each protein match.
+{{:userguide:pride_onepeptideinprideinspector.png|}}
+So, the number of peptides in Pride Inspector is generally bigger than the peptide count in a User context.
