WGS performance metrics for the congruently/non-congruently classified samples between array/WGS and original coverage and downsampled WGS-derived data

This file contains WGS performance metrics for all the samples (n = 67). The data was derived using the CollectWgsMetrics tool from Picard tools (https://broadinstitute.github.io/picard/). The performance metrics include PCT_EXC_MAPQ, representing the fraction of aligned bases that were filtered out because they were in reads with low mapping quality and PCF_EXC_BASEQ, representing the fraction of aligned bases that were filtered out because they were of low base quality. The Type column indicates whether the sample relates to the tumour or normal tissue of a given donor. The Congruency column indicates whether a given sample was congruently (con) v/s non-congruently classified (ncon) classified between original and downsampled WGS data. The Metric column indicates the WGS performance metric of interest. The value column provides the numerical value of the WGS performance metric of interest for the tumour or normal sample of a particular donor.<br>

本文件涵盖全部67个样本（n=67）的全基因组测序（Whole Genome Sequencing, WGS）性能指标数据。该数据集通过Picard工具集（https://broadinstitute.github.io/picard/）中的CollectWgsMetrics工具生成。本次统计的性能指标包含PCT_EXC_MAPQ与PCF_EXC_BASEQ：其中PCT_EXC_MAPQ表示因携带低比对质量reads而被过滤的比对碱基占比；PCF_EXC_BASEQ则表示因碱基质量较低而被过滤的比对碱基占比。Type（样本类型）列用于标识某一供体的样本属于肿瘤组织还是正常组织。Congruency（一致性）列用于标注某一样本在原始WGS数据与降采样WGS数据间的分类结果是否一致，其中"con"代表分类结果一致，"ncon"代表分类结果不一致。Metric（指标）列用于标记所关注的WGS性能指标类型。Value（数值）列则提供特定供体的肿瘤或正常样本所对应目标WGS性能指标的具体数值。
