  description: '**status**: released


    **biological\_replicates**: Rep 1


    **summary**: female adult (75 years)


    **output\_type**: pseudoreplicated peaks


    **audit\_internal\_action**: Archived analysis {ENCAN817LLY|/analyses/ENCAN817LLY/}
    has in progress subobject quality standard {encode3-histone-chip|/quality-standards/encode3-histone-chip/}


    **audit\_warning**: Processed redacted alignments file {ENCFF021NCO|/files/ENCFF021NCO/}
    processed by ChIP-seq ENCODE3 hg19 pipeline has 12478262 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**: 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 alignments file {ENCFF021NCO|/files/ENCFF021NCO/}
    processed by ChIP-seq ENCODE3 hg19 pipeline was generated from a library with
    PBC2 value of 9.97.'
