in this case , it is found that the methods can : ( i ) distinguish slices containing signal from those containing only noise , ( ii ) locate slices containing overlapping signals , and ( iii ) in some cases to segregate slices with unique aspects such as those from terminal nucleotides , overlapping signals , purine-h8 , pyrimidine-h6 and adenine-h2 containing slices .
