The visalization presents an integrated display of:
The central panel shows an interactive peptagram display. The peptagram consists of rows where each row represents the peptides identified for each separate experiment. You can click on the peptides which will select both the experiment for Peptide-Spectrum Matches and the Spectrum in the Spectrum Viewer.
The Sequence below will scroll to the part of the protein that you just clicked on.
All identified proteins are shown on the left, withe the peptides illustrated in a the bar graph. All proteins are normalized to the same width of the screen as there is too great a difference between protein sequence lengths to show this in proportion. Clicking on a protein on this light will bring up a detailed display of the sequence, with the peptides tintedtexted by clickable links. This list can be sorted by the pop-up menu at the top of the section. All attributes displayed in the protein info panel can be sorted against.
Several keyboard shortcuts have been included, and these are labeled above the sub-headings of the relevant section. These are:
Can be done using the built-in web-browser search. All the text for the proteins, and principal seqid are always available in the protein-list view, and thus searchable.
Below that is the list of peptide spectrum matches, listed by their positions in the sequence and the sequnce. If modifications were read in, they will be tintedtexted. Click on thes will display the MS/MS spectra if available.
If the MS/MS spectra have been loaded then, if a peptide-spectrum match is clicked, a simple spectrum viewer is shown of the top 50 peaks found in the peptide-spectrum match. Below the viewer is an interactive ion table, showing b-ions and y-ions. By click on the labels at the top of the table, different charge states for the b-ions and y-ions are displayed, both in the the table and the spectrum viewer. Clicking on the viewer will zoom to the nearest peak, where the viewer will scale to the height of the zoomed peak, which should now be in the middle of the viewer. Clicking again on the viewer will zoom out. The viewer automatically scales to the minimum-maxium peak m/z values.
