Weights of nine genomic features in the trained logistic regression models for known ncRNA, CDS, and UTR
[i] aDNA conservation is the nucleotide identity in each window of the genome alignment between C. elegans and C. briggsae.
[ii] bThe free energy of RNA secondary structure is measured by the Z-score of RNA's folding ΔG°37 calculated by Dynalign. A stable structure favors low free energy.
[iii] cRNA secondary structure conservation is measured by the SCI (structure conservation index) between C. elegans and C. briggsae.
[iv] dProtein sequence conservation is the tblastx score divided by DNA identity in the C. elegans and C. briggsae DNA alignment.
[v] eThe maximum expression value from different biological samples produced by the same technology is used.
