All the three datasets have been collected from http://dmb.iasi.cnr.it/blog.php and all these datasets have been used in earlier studies (Van Velzen et al., 2012; Weitschek et al., 2014).

ED-I contains real barcode sequences different species belong to  Cypreidae family,Drosophila, Inga trees, Fish, Bird and Bat.

ED-II contains real barcode sequences of diverged species belong to Cypreidae family, Drosophila, and Inga trees

SD-I contains 100 sets (100 training and 100 test sets) of simulated barcode sequences belong to 50 species
