    \ \n\n**output\\_type**: pseudoreplicated peaks\n\n**audit\\_internal\\_action**:\
    \ Released analysis {ENCAN490CQL|/analyses/ENCAN490CQL/} has in progress subobject\
    \ quality standard {encode4-histone-chip|/quality-standards/encode4-histone-chip/}\n\
    \n**audit\\_not\\_compliant**: Processed redacted alignments file {ENCFF794AWE|/files/ENCFF794AWE/}\
    \ processed by ChIP-seq ENCODE4 v1.7.0 GRCh38 pipeline has 8038898 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/})\n\n**audit\\\
    _not\\_compliant**: NRF (Non Redundant Fraction) is equal to the result of the\
    \ division of the number of reads after duplicates removal by the total number\
    \ of reads. 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 redacted alignments file {ENCFF794AWE|/files/ENCFF794AWE/}\
    \ processed by ChIP-seq ENCODE4 v1.7.0 GRCh38 pipeline was generated from a library\
    \ with NRF value of 0.25.\n\n**audit\\_not\\_compliant**: 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. ENCODE processed redacted alignments file {ENCFF794AWE|/files/ENCFF794AWE/}\
    \ processed by ChIP-seq ENCODE4 v1.7.0 GRCh38 pipeline was generated from a library\
    \ with PBC1 value of 0.26.\n\n**audit\\_warning**: PBC2 (PCR Bottlenecking Coefficient\
    \ 2, M1/M2) is the ratio of the number of genomic locations where exactly one\
    \ read maps uniquely (M1) to the number of genomic locations where two reads map\
    \ uniquely (M2). 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.\
    \ PBC2 value > 10 is recommended, but > 3 is acceptable. ENCODE processed redacted\
