Dotplot
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.
GUI-controls:
- 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.
Highlighting:
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.
