RMDsignatures_exposures_k=13_nFact13_n=4221.csv

Regional mutation density (RMD) signatures obtained after appling NMF into a matrix of mutation density across 1Mb windows along the genome for 4221 tumor samples. The values provided (NMF exposures) represent the number of mutations that comes from each specific signature in each sample. The exposures are not normalized.区域突变密度（Regional Mutation Density, RMD）突变特征，是通过对4221份肿瘤样本全基因组1Mb窗口内的突变密度矩阵应用非负矩阵分解（Non-negative Matrix Factorization, NMF）后获得的。本次提供的数值（NMF暴露值，NMF exposures）代表了每个样本中源自各特定突变特征的突变数目。该暴露值未经过标准化处理。
