A dot-plot is a correlogram of two sequence .
Each dot in the pane represents a pair of residues from either
protein. The brightness of the dot is mainly determined by the
similarity of both amino acids according to the blosum62 matrix. A
number of positions up and downstream are taken into account
with declining weight.
- Slider: The width of the low pass filter with Co-sinus weights.
- Slider: The brightness of the entire plot.
- Combo box: The proteins of the X axis and Y axis.
- Toggle : View the alignment trace according to the alignment panel.
Positions can be highlighted in the pane by clicking. Correspond sequence positions are highlighted.
Periodicity Sequence periodicity becomes evident by more than one white oblique trace. See PDB:1g61 for an example.
