Table 1.
The numbers of OTUs observed at the 0.03 and 0.05 distance levels and at the peak positions for the four methods
| ESPRIT-AL | ESPRIT-Tree | UCLUST | CD-HIT | |
|---|---|---|---|---|
| 0.03 level | 1045 (19) | 1137 (30) | 1193 (26) | 920 (23) |
| 0.05 level | 241 (7) | 268 (6) | 362 (11) | 314 (9) |
| peak NMI-species | 402 (9) | 400 (9) | 590 (13) | 314 (9) |
| peak NMI-genus | 190 (5) | 176 (7) | 216 (6) | 243 (7) |
The ground truths of the numbers of species and genera are 371±7 and 170±5, respectively. The number in the parenthesis is one SD. ESPRIT-Tree and ESPRIT with the average linkage function (ESPRIT-AL) yielded the most accurate estimates of microbial diversity among the four methods.
