MFE metrics and siRNA mapping abundances

Table providing MFE metrics and siRNA information 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
