Overview
Metrics that are calculated during the process of marking duplicates within a stream of SAMRecords using the UmiAwareDuplicateSetIterator.This table summarizes the values that are specific to this metric.
| Metric | Summary |
|---|---|
| LIBRARY |
Library that was used to generate UMI data. |
| MEAN_UMI_LENGTH |
Number of bases in each UMI |
| OBSERVED_UNIQUE_UMIS |
Number of different UMI sequences observed |
| INFERRED_UNIQUE_UMIS |
Number of different inferred UMI sequences derived |
| OBSERVED_BASE_ERRORS |
Number of errors inferred by comparing the observed and inferred UMIs |
| DUPLICATE_SETS_IGNORING_UMI |
Number of duplicate sets found before taking UMIs into account |
| DUPLICATE_SETS_WITH_UMI |
Number of duplicate sets found after taking UMIs into account |
| OBSERVED_UMI_ENTROPY |
Entropy (in base 4) of the observed UMI sequences, indicating the effective number of bases in the UMIs. If this is significantly smaller than UMI_LENGTH, it indicates that the UMIs are not distributed uniformly. |
| INFERRED_UMI_ENTROPY |
Entropy (in base 4) of the inferred UMI sequences, indicating the effective number of bases in the inferred UMIs. If this is significantly smaller than UMI_LENGTH, it indicates that the UMIs are not distributed uniformly. |
| UMI_BASE_QUALITIES |
Estimation of Phred scaled quality scores for UMIs |
| PCT_UMI_WITH_N |
The percentage of reads that contain an UMI that contains at least one N |
