  description: '**status**: released


    **biological\_replicates**: Rep 1, Rep 2


    **summary**: female embryo (5 days)


    **output\_type**: pseudoreplicated peaks


    **audit\_internal\_action**: Released analysis {ENCAN024YMA|/analyses/ENCAN024YMA/}
    has in progress subobject document {402b17eb-31af-42ba-9661-e889dcc466b9|/documents/402b17eb-31af-42ba-9661-e889dcc466b9/}


    **audit\_internal\_action**: Released analysis {ENCAN024YMA|/analyses/ENCAN024YMA/}
    has in progress subobject quality standard {encode4-histone-chip|/quality-standards/encode4-histone-chip/}


    **audit\_not\_compliant**: Processed unfiltered alignments file {ENCFF034IAZ|/files/ENCFF034IAZ/}
    processed by ChIP-seq ENCODE4 v1.6.1 GRCh38 pipeline has 30718809 mapped reads.
    The minimum ENCODE standard for each replicate in a ChIP-seq experiment targeting
    H3K9me3-human and investigated as a broad histone mark is 35 million mapped reads.
    The recommended value is > 45 million, but > 35 million is acceptable. (See {ENCODE
    ChIP-seq data standards|/data-standards/chip-seq/})


    **audit\_warning**: Processed unfiltered alignments file {ENCFF353MJE|/files/ENCFF353MJE/}
    processed by ChIP-seq ENCODE4 v1.6.1 GRCh38 pipeline has 42876021 mapped reads.
    The minimum ENCODE standard for each replicate in a ChIP-seq experiment targeting
    H3K9me3-human and investigated as a broad histone mark is 35 million mapped reads.
    The recommended value is > 45 million, but > 35 million is acceptable. (See {ENCODE
    ChIP-seq data standards|/data-standards/chip-seq/})


    **audit\_warning**: 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 alignments file {ENCFF657TOJ|/files/ENCFF657TOJ/}
    processed by ChIP-seq ENCODE4 v1.6.1 GRCh38 pipeline was generated from a library
    with NRF value of 0.74.


    **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. ENCODE processed alignments
    file {ENCFF657TOJ|/files/ENCFF657TOJ/} processed by ChIP-seq ENCODE4 v1.6.1 GRCh38
    pipeline was generated from a library with PBC1 value of 0.74.


    **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 alignments file {ENCFF657TOJ|/files/ENCFF657TOJ/}
    processed by ChIP-seq ENCODE4 v1.6.1 GRCh38 pipeline was generated from a library
    with PBC2 value of 3.66.'
