Similarity Matrix

A similarity matrix is a matrix of scores which show the similarities between two data points. They are generally used in sequence alignment. The higher the score the more similar characters it receives. This is a similarity matrix comparing different types of organisms. The red line that goes down the center suggest high similarity or exactness. The different shades of blue (and green) represent how similar the organisms are.
