| Keyword | Description | Clones* |
|---|---|---|
| HTGS_FULLTOP | 2 x 384 paired-end attempts (6X coverage); completed shotgun phase; initial assembly | 1231 |
| HTGS_PREFIN | Completed automated improvement phase (AutoFinish) | 501 |
| HTGS_ACTIVEFIN | Active work being done by a finisher | 1061 |
| HTGS_IMPROVED | Finished sequence in gene regions; improved regions will be indicated; once order and orientation of improved segments are confirmed, a comment will be added to indicate this | 294 |
