    \ processed by DNase-seq ENCODE4 v3.0.0-alpha.2 GRCh38 pipeline ( {ENCPL848KLD|/pipelines/ENCPL848KLD/}\
    \ ) for GRCh38 assembly has 22082019 mapped reads. According to ENCODE standards,\
    \ conventional DNase-seq profile requires a minimum of 20 million uniquely mapped\
    \ reads to generate a reliable SPOT (Signal Portion of Tags) score. The recommended\
    \ value is > 50 million. For deep, foot-printing depth DNase-seq 150-200 million\
    \ uniquely mapped reads are recommended. (See {ENCODE DNase-seq data standards|/data-standards/dnase-seq-encode4/})\n\
    \n**audit\\_warning**: Signal Portion of Tags (SPOT) is a measure of enrichment,\
    \ analogous to the commonly used fraction of reads in peaks metric. ENCODE processed\
    \ alignment files {ENCFF123FCM|/files/ENCFF123FCM/} processed by DNase-seq ENCODE4\
    \ v3.0.0-alpha.2 GRCh38 pipeline ({ENCPL848KLD|/pipelines/ENCPL848KLD/}) for GRCh38\
    \ assembly  have a SPOT1 score of 0.31. According to ENCODE standards, SPOT1 score\
    \ of 0.4 or higher is considered a product of high quality data. Any sample with\
    \ a SPOT1 score <0.3 should be targeted for replacement with a higher quality\
    \ sample, and a SPOT1 score of 0.25 is considered minimally acceptable SPOT1 score\
    \ of 0.25 is considered minimally acceptable for rare and hard to find primary\
    \ tissues. (See {ENCODE DNase-seq data standards|/data-standards/dnase-seq-encode4/})"
