Data views. a) Partial screenshot of the protein list view in PrestOMIC. The Experiment each of the proteins was found in is listed, as is the unique identification number for the protein in the Protein_Quantification table, the relative quantification of each protein (in this case sequence coverage was used) and the validation status of each protein. Most proteins reported would obviously be validated, but an investigator might also want to report contaminants, for instance, and that status could be indicated in this last column. Clicking on the hyperlinked Experiment retrieves all the peptides identified in that Experiment (not shown) and clicking on the hyperlinked. Protein_Quantification number brings up b) the information specific to that protein in that particular Experiment. Each peptide identified is highlighted and hyperlinked. Clicking on the link brings up additional information about the specific peptide, if it is available, such as the observed mass-to-charge ratio (m/z), the observed charge state(s), modifications and the fragment spectra used in the identification.
