| | The Chi2 method
On the main chi2 visualization screen, the chi2 graph is displayed along the whole DNA sequence. Chi2 values over a given threshold are reported. The contingency tables for the current chi2 point are displayed and can be detailed on a further visualization level. The computation of the numbers of each nucleotid, expected and observed in each codon position, as well as the partial chi2 and the chi2 values is explained.
