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/}) **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 {ENCFF091KTX|/files/ENCFF091KTX/} processed by DNase-seq ENCODE4 v3.0.0 GRCh38 pipeline ({ENCPL848KLD|/pipelines/ENCPL848KLD/}) for GRCh38 assembly have a SPOT1 score of 0.37. 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.
