An NRF value in the range 0 - 0.5 is poor complexity, 0.5 - 0.8 is moderate complexity, and > 0.8 high complexity. NRF value > 0.8 is recommended, but > 0.5 is acceptable. ENCODE processed alignments file {ENCFF825ZUF|/files/ENCFF825ZUF/} processed by ChIP-seq ENCODE3 GRCh38 pipeline was generated from a library with NRF value of 0.48. **audit\_warning**: Processed alignments file {ENCFF825ZUF|/files/ENCFF825ZUF/} processed by ChIP-seq ENCODE3 GRCh38 pipeline has 11406069 usable fragments. The minimum ENCODE standard for each replicate in a ChIP-seq experiment targeting H3K27ac-human and investigated as a narrow histone mark is 10 million usable fragments. The recommended value is > 20 million, but > 10 million is acceptable. (See {ENCODE ChIP-seq data standards|/data-standards/chip-seq/}) **audit\_warning**: PBC1 (PCR Bottlenecking Coefficient 1, M1/M\_distinct) is the ratio of the number of genomic locations where exactly one read maps uniquely (M1) to the number of genomic locations where some reads map (M\_distinct). A PBC1 value in the range 0 - 0.5 is severe bottlenecking, 0.5 - 0.8 is moderate bottlenecking, 0.8 - 0.9 is mild bottlenecking, and > 0.9 is no bottlenecking. PBC1 value > 0.9 is recommended, but > 0.8 is acceptable.

A PBC2 value in the range 0 - 1 is severe bottlenecking, 1 - 3 is moderate bottlenecking, 3 - 10 is mild bottlenecking, > 10 is no bottlenecking.
