Abstract:
This paper presents a clustering and visualization
technique for analyzing dihedral angles of large protein
sequences. The clustering is used for discovering and
grouping those similar dihedrals while the visualization
can display and navigate sequences of dihedral angles of
several proteins as well as their clustered property. In
order to visualize a very large sequence of hundred
thousands of dihedral signals, we plot them on a spiral
coordinate system. This spiral visualization ensures the
linear distribution without distortion or interruption of a
very long sequence of points. A clustering algorithm is
also provided to group those dihedral signals into
different clusters so that it can enhance the analysis
process. Our system can also zoom to display a number
of selected proteins interactively.
