sORF finder: a program package to identify small open reading frames with high coding potential

SUMMARY: sORF finder is a program package for identifying small open reading frames (sORFs) with high-coding potential. This application allows the identification of coding sORFs according to the nucleotide composition bias among coding sequences and the potential functional constraint at the amino acid level through evaluation of synonymous and non-synonymous substitution rates.
