Table S5. MFE metrics and siRNA mapping abundances

Figure S5, providing MFE metrics and siRNA informaion on each feature analyzed. Columns: "FeatureID" = Unique designation for each feature. Format is "Feature type"::"chromosome":"start pos"-"end pos" "MFE_Region_Length" = Length of region < -40 kcal/mol in feature "nonMFE_Region_Length" = Length of region > -40 kcal/mol in feature "element" = Feature type "family" = superfamily or lower designation "siRNA_length" = 21, 22, or 24-nt siRNA "measure" = Counts per nucleotide "MFE" = siRNA counts per nucleotide in low MFE regions "nonMFE" = siRNA counts per nucleotide in high MFE regions "CountsPerNT" = overall counts per nucleotide across feature "minMFE" = minimum MFE "meanMFE" = mean (average) MFE "MFEvariance" = variance across windows "PctMFEltthresh" = proportion of windows below -40 kcal/mol图S5提供了本次分析中各特征的最小自由能（Minimum Free Energy, MFE）相关指标以及小干扰RNA（small interfering RNA, siRNA）信息。各列含义如下： "FeatureID"：各特征的唯一标识符，格式为“特征类型::染色体:起始位置-终止位置” "MFE_Region_Length"：特征中最小自由能低于-40 kcal/mol的区域长度 "nonMFE_Region_Length"：特征中最小自由能高于-40 kcal/mol的区域长度 "element"：特征类型 "family"：超家族或更低层级的分类命名 "siRNA_length"：长度为21、22或24 nt的小干扰RNA "measure"：每核苷酸的计数 "MFE"：低最小自由能区域内每核苷酸的小干扰RNA计数 "nonMFE"：高最小自由能区域内每核苷酸的小干扰RNA计数 "CountsPerNT"：特征整体范围内每核苷酸的总计数 "minMFE"：最小自由能最小值 "meanMFE"：最小自由能平均值 "MFEvariance"：各窗口的最小自由能方差 "PctMFEltthresh"：低于-40 kcal/mol的窗口占比
