Assay of Transposase-Accessible Chromatin by deep sequencing (ATAC-seq) has been widely used to profile the chromatin accessibility genome-wide. For the absence of an integrated scheme for deep data mining of specific biological issues, here we present ATAC-pipe, an efficient pipeline for general analysis of chromatin accessibility data obtained from ATAC-seq experiments. ATAC-pipe captures information includes not only the quality of original data and genome-wide chromatin accessibility but also signatures of significant differential peaks, transcription factor (TF) occupancy and nucleosome positions around regulatory sites. In addition, ATAC-pipe automatically converts statistic results into intuitive plots at publication quality, such as the read length distribution, heatmaps of sample clustering and cell-type-specific regulatory elements, enriched TF occupancy with motifs footprints and TF-driven regulatory networks. ATAC-pipe provides convenient workflow for researchers to study chromatin accessibility and gene regulation. Availability https://github.com/QuKunLab/ATAC-pipe.
利用转座酶可及染色质测序(ATAC-seq)进行分析,已被广泛用于全基因组范围内研究染色质可及性。由于缺乏针对特定生物学问题的深度数据挖掘的综合方案,我们在此介绍了 ATAC-pipe,这是一种用于分析 ATAC-seq 实验获得的染色质可及性数据的高效分析流程。ATAC-pipe 捕获的信息不仅包括原始数据的质量和全基因组染色质可及性,还包括显著差异峰、转录因子(TF)占据和调控位点附近核小体位置的特征。此外,ATAC-pipe 会自动将统计结果转换为直观的图谱,达到发表质量,例如读取长度分布、样本聚类的热图以及细胞类型特异性调控元件、富含 TF 占据的基序足迹和 TF 驱动的调控网络。ATAC-pipe 为研究人员研究染色质可及性和基因调控提供了便捷的工作流程。可获取网址:https://github.com/QuKunLab/ATAC-pipe。
