Figure 1
A screen capture of SnipViz displaying the DNA sequence of a gene for 22 different strains of S. cerevisiae . The top rectangle is a graphical representation of the whole sequence (1,731 nucleotides long) that serves as a whole-sequence navigation bar. The dashed box indicates the currently-viewed segment of the sequence and may be clicked and dragged to the desired location in the sequence. The red bars indicate locations of variation in the sequence among all the strains. The bottom left displays a hierarchically clustered list of the sequence labels, and the bottom right displays the sequences. The blue bars highlight columns in the sequence display where variation occurs.
