No Common Sites

For the sequences and data subset options selected, MEGA found zero common sites. If you selected the complete deletion option then you might achieve better results using the pairwise deletion option, as complete deletion removes all sites containing a gap in any part of the alignment. If you selected the pairwise deletion option then MEGA was unable to calculate the distance between one and several of the sequence pairs in the alignment. To identify such pairs compute a pairwise distance matrix using the p-distance method and look for the word "n/c" in place of the pairwise distance value.
