The visualization is laid out as shown below; the view names are referred to in the text.
The main view in this visualization shows a small circle for each bonded nitrogen/hydrogen pair for which chemical shifts are available for both atoms. Each circle is located by the N chemical shift on the Y axis and the H chemical shift on the X axis. For the amino acid(s) selected in the amino acid view, all of the appropriate circles are filled in with a red dot. For the residues selected in the residue list view, the "normal" circles are surrounded by a yellow circle.
The amino acid view shows the three-letter amino acid abbreviations, along with the number of occurrences of each amino acid in the molecule. The cursor selects the amino acid(s) to highlight in the main view, residue list view, and residue scroll view. (Note that the cursor can be enlarged to select more than one amino acid; it can also be moved to the blank region at the top to select no amino acids.)
The residue list view shows a list of single-letter amino acid abbreviations for the residue sequence. The residues selected (within the yellow cursor) are highlighted in yellow in the main view. "Normal" residues are shown in violet; residues for which there is no 1H-15N data available are shown in pink; and residues of the amino acid selected in the amino acid view are show in red.
The residue scroll view selects the range of residues shown in the residue list view (this is done because showing all residues would often make the letters unreadable). The colors are the same as in the residue list view.
The info view shows the BMRB accession number and generation date of the visualization; display the view help (F1 key) to see the Peptide-CGI version and exact generation timestamp.
