Indicator Vectors

Sirovich L, Stoeckle MY, Zhang Y (2009) A Scalable Method for Analysis and Display of DNA Sequences. PLoS ONE 4(10): e7051. doi:10.1371/journal.pone.0007051

From the Abstract:

The indicator vectors preserved DNA character information and provided quantitative measures of correlations among taxonomic groups. This method is scalable to the largest datasets envisioned in this field, provides a visually-intuitive display that captures relational affinities derived from sequence data across a diversity of life forms, and is potentially a useful complement to current tree-building techniques for studying evolutionary processes based on DNA data.
