\paragraph*{Phosphopeptide mode}
In this mode, only peptides containing one or more phosphorylation site are taken into account.
It builds a phosphoisland list. A phosphoisland is a merge of phosphopeptides sharing the same peptide sequence (possible overlaps). A phosphoisland could be present in one or several proteins : these phosphoislands are represented as subgroups.
The proteins sharing one or more subgroups of phosphoislands are represented by groups.
In this mode, only peptides containing one or more phosphorylation site are taken into account. These peptides are called phosphopeptides. Phosphopeptides sharing the same peptide sequence (possible overlaps) are represented by subgroups. A phospisland is a set of phophopeptides sharing the same peptide sequence, specific to a protein. Thus PhosphoIslands in the same subgroups share the same set of phosphopeptides.
Subgroups are grouped together if they share at least one protein.

\label{ods_phosphopeptide_tab}
This tab displays the protein abundance index (PAI) and the exponentially modified PAI (emPAI) by sample, for each top protein of a subgroup. This is convenient to have an idea of the presence/absence of a subgroup of proteins in a sample, and an indication about relative abundance in each samples.
This tab displays details about each identified phosphopeptides. A phosphopeptide is a merge of identified peptides including phosphorylations and sharing the same unique sequence + \mhplus mass modification.
