smr格式besd文件中提取cis-qtls数据并做分析 虽然smr_query_file可以提取出来顺式的qtl数据,但是提取出来后还要改成模板snp的格式,不是很方便,所以下面新增了一个方法,可以批量提取,并且直接进行mr分析。 使用下面的方法,请保证包更到最新,...
cis和trans本质上就是通过SNP位点和gene之间的距离进行区分,首先对所有的SNP-gene对进行计算,然后根据距离阈值将结果进行拆分,小于阈值的SNP-gene对归于cis-eQTL, 大于阈值的归于trans-eQTL。
通过开发“增强子陷阱”方法用于识别和鉴定未知的CRMs。这种方法通量低、只能对单个CRMs精细鉴定且在对小基因组且易于转化的物种中非常有用,但对于大基因组的生物例如棉花、玉米等仍旧十分困难;其他的方法就是使用数量性状基因座(QTL)和精细定位方法。 高通量测序技术的出现极大的促进了在全基因组范围内识别CRMs。通过利...

We compared mixQTL with two methods: using either only allele-specific counts (ascQTL) or total counts (trcQTL). See details in Supplementary Notes 4.1. All three methods had calibrated type I errors (Fig. 2a and Supplementary Fig. 1). mixQTL outperformed both trcQTL and ascQTL in all ...
如果原报告灯具长度>1.6米,需要提供样品在开阔场或半电波暗室中使用60cm的环形天线置于3m的环境中进行测试9kHz-30MHz的辐射骚扰; 如果原报告产品是球泡灯、节能灯等自镇流灯具类产品,需提供样品用新的灯罩进行端子骚扰电压的测试。 2、对于全新项目,则完全按照CISPR 15: 2018的要求进行评估。
Genome-wide association studies have reported 11 regions conferring risk of high-grade serous epithelial ovarian cancer (HGSOC). Expression quantitative trait locus (eQTL) analyses can identify candidate susceptibility genes at risk loci. Here we evaluat
QTL types displayed a similar genomic distribution (Additional file1: Fig. S4.1i) with hcmQTLs having on average a stronger association with the peak height (i.e., higher beta values in a linear regression of genotype and normalized peak counts; Additional file1: Fig. S4.1j). Both QTL ...
