|     1037 samples [4296..5332]
|     0.185 of the curve [0.766__0.950]
|   Segment [1] from curve   46 (reversed)
|     1014 samples [2979..3992]
|     0.164 of the curve [0.481__0.645]
| Candidate after realignment and trimming:
|   Candidate index = 21
|   Segment [0] from curve   45
|      513 samples [4740..5252]
