  description: '**status**: released


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


    **summary**: male adult (36 years)


    **output\_type**: pseudoreplicated peaks


    **audit\_error**: Alignment file {ENCFF364RYN|/files/ENCFF364RYN/} processed by
    ATAC-seq ENCODE4 v1.10.0 GRCh38 pipeline has 12745523 usable fragments. According
    to ENCODE4 standards, ATAC-seq assays processed by the uniform processing pipeline
    should have > 25 million usable fragments. 20-25 million is acceptable and < 15
    million is not compliant.


    **audit\_internal\_action**: Released analysis {ENCAN077FIR|/analyses/ENCAN077FIR/}
    has in progress subobject quality standard {encode4-atac-seq|/quality-standards/encode4-atac-seq/}


    **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 < 0.7 is poor complexity, between 0.7 and 0.9 is moderate
    complexity, and >= 0.9 high complexity. NRF value > 0.9 is recommended, but >
    0.7 is acceptable. ENCODE processed file {ENCFF364RYN|/files/ENCFF364RYN/} processed
    by ATAC-seq ENCODE4 v1.10.0 GRCh38 pipeline was generated from a library with
    NRF value of 0.538814.


    **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 > 0.7 is acceptable. ENCODE processed file
    {ENCFF364RYN|/files/ENCFF364RYN/} processed by ATAC-seq ENCODE4 v1.10.0 GRCh38
    pipeline was generated from a library with a PBC1 value of 0.50.


    **audit\_not\_compliant**: According to ENCODE4 standards, overlap peaks files
    in ATAC-seq assays processed by the uniform processing pipeline should have FRiP
    (fraction of reads in called peak regions) scores > 0.3. FRiP scores 0.2-0.3 are
    acceptable, and < 0.2 are not compliant. {ENCFF929NTI|/files/ENCFF929NTI/} processed
    by ATAC-seq ENCODE4 v1.10.0 GRCh38 pipeline  has a FRiP score of 0.16.


    **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 file {ENCFF364RYN|/files/ENCFF364RYN/}
    processed by ATAC-seq ENCODE4 v1.10.0 GRCh38 pipeline was generated from a library
    with a PBC2 value of 1.78.


    **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 < 0.7 is poor complexity, between 0.7 and 0.9 is moderate
    complexity, and >= 0.9 high complexity. NRF value > 0.9 is recommended, but >
    0.7 is acceptable. ENCODE processed file {ENCFF347LNL|/files/ENCFF347LNL/} processed
    by ATAC-seq ENCODE4 v1.10.0 GRCh38 pipeline was generated from a library with
    NRF value of 0.833455.


    **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 > 0.7 is acceptable. ENCODE processed file
    {ENCFF347LNL|/files/ENCFF347LNL/} processed by ATAC-seq ENCODE4 v1.10.0 GRCh38
    pipeline was generated from a library with a PBC1 value of 0.83.


    **audit\_warning**: According to ENCODE4 standards, ATAC-seq assays processed
    by the uniform processing pipeline should have either >150k reproducible peaks
    in an overlap peaks file, or >70k in an IDR thresholded peaks file. 100-150k or
    50-70k peaks respectively is acceptable, and <100k or <50k respectively is not
    compliant. File(s) {ENCFF929NTI|/files/ENCFF929NTI/} (overlap peaks) and {ENCFF603GBI|/files/ENCFF603GBI/}
    (IDR thresholded peaks) processed by ATAC-seq ENCODE4 v1.10.0 GRCh38 pipeline
    have 89161 and 56932 peaks.'

    submitter_comment: This dataset has been released as part of a larger biosample
      and assay collection, despite noncompliance with ENCODE quality standards, due
      to lack of sample material to reattempt the assay.
