  summary: 'ChIP-seq ENCSR929AXP [TISSUE: Homo sapiens muscle layer of duodenum tissue
    male adult (59 years), TARGET: H3K27me3]'
  description: '**status**: released


    **biological\_replicates**: Rep 1


    **summary**: male adult (59 years)


    **output\_type**: pseudoreplicated peaks


    **audit\_internal\_action**: Archived analysis {ENCAN067TVG|/analyses/ENCAN067TVG/}
    has in progress subobject quality standard {encode3-histone-chip|/quality-standards/encode3-histone-chip/}


    **audit\_not\_compliant**: Processed redacted alignments file {ENCFF944EAQ|/files/ENCFF944EAQ/}
    processed by ChIP-seq ENCODE3 hg19 pipeline has 32711960 usable fragments. The
    minimum ENCODE standard for each replicate in a ChIP-seq experiment targeting
    H3K27me3-human and investigated as a broad histone mark is 20 million usable fragments.
    The recommended value is > 45 million, but > 35 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. ENCODE processed redacted
    alignments file {ENCFF944EAQ|/files/ENCFF944EAQ/} processed by ChIP-seq ENCODE3
    hg19 pipeline was generated from a library with PBC1 value of 0.90.


    **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 {ENCFF944EAQ|/files/ENCFF944EAQ/}
    processed by ChIP-seq ENCODE3 hg19 pipeline was generated from a library with
    PBC2 value of 9.49.'
