Figure 3From: TETRA: a web-service and a stand-alone program for the analysis and comparison of tetranucleotide usage patterns in DNA sequencesDotplot of Z-scores for the tetranucleotide frequencies of two Bacilli. A regression line is calculated as well as the Pearson correlation coefficient (0.823). Hovering with the mouse over a dot shows a small information window with the tetranucleotide(s) the spot is referring to (as shown for GATC in this case).Back to article page
