从 BAM 文件计算;RiP 指仅计算落入 consensus peaksets 的 reads; backgroud 指根据背景信号进行均一化,原理是 ATAC-Seq 得到的 peak 区域是比较小的,大约在 100-600bp. 如果将基因组分成大的 bin 比如 15000bp 大小,理论上这种大小 bin 的信号差异应该是技术误差而不是生物学差异。
ATAC-seq (Assay for Transposase-Accessible Chromatin using high-throughput sequencing) is a sequencing assay for investigating genome-wide chromatin accessibility. The assay applies a Tn5 Transposase to insert sequencing adapters into accessible chromatin, enabling mapping of regulatory regions across the ge...
For this reason, our method evaluation primarily relied on comparing scATAC-seq signals reconstructed from a single cell or by pooling multiple cells to bulk DNase-seq or ATAC-seq signals. In this regard, one may view single cells as random samples from a cell population, and the bulk signal...
Statistical models and methods designed for gene expression analysis are widely used in the analysis of ATAC-seq data. However, unlike RNA transcripts, which can have thousands of copies per cell, the ATAC-seq signals of a given genomic region can be obtained from only two allelic DNA copies....
2022年2月28日,Genome Biology在线发表了中国科学院上海营养与健康研究所邵振课题组题为“HyperChIP: identification of hypervariable signals across ChIP-seq or ATAC-seq samples”的方法学论文,报道了其开发的HyperChIP计算模型。它能对多个ChIP/ATAC-seq样本间信号强度差异进行统计建模,识别高变信号基因组区域(hype...
