  description: "**status**: released\n\n**biological\\_replicates**: Rep 1, Rep 2\n\
    \n**summary**: \n\n**output\\_type**: replicated peaks\n\n**audit\\_internal\\\
    _action**: Archived analysis {ENCAN825SQS|/analyses/ENCAN825SQS/} has in progress\
    \ subobject quality standard {encode3-histone-chip|/quality-standards/encode3-histone-chip/}\n\

    \ processed by ChIP-seq ENCODE3 GRCh38 pipeline has 17290018 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.\

    _warning**: Processed alignments file {ENCFF204UGN|/files/ENCFF204UGN/} processed\

    \ 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.\

    _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\
