The differences between coding versus noncoding trees were not solely due to shorter sequence length of the coding data, because the full coding data set (13.3 million bp for c123) produced a tree with fully supported (100 % BS) relationships that were incongruent with those fully supported in the intron (19.3 million bp), TENT (37.4 million bp without the third codon position), and WGT (322.1 million bp)(Figs. 2 and 5B, and table S3).
