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
