ZINBA(零膨胀负二项算法)识别在各种ChIP-seq和相关的下一代测序实验(DNA-seq)中富集的基因组区域,在信噪比范围内调用广泛和狭窄的富集模式。ZINBA模型和解释了与背景或实验信号共变的因素,如G/C含量,并鉴定了具有复杂局部拷贝数变化的基因组中的富集。ZINBA为在具有挑战性的基因组背景下分析DNA-seq实验提供了一个单一的统一框架。软件网站:http://code.google.com/p/zinba/
ZINBA (Zero-Inflated Negative Binomial Algorithm) identifies genomic regions enriched in a variety of ChIP-seq and related next-generation sequencing experiments (DNA-seq), calling both broad and narrow modes of enrichment across a range of signal-to-noise ratios. ZINBA models and accounts for factors that co-vary with background or experimental signal, such as G/C content, and identifies enrichment in genomes with complex local copy number variations. ZINBA provides a single unified framework for analyzing DNA-seq experiments in challenging genomic contexts. Software website: http://code.google.com/p/zinba/
