While preparing sequence submissions for GenBank, I was perplexed by
the following questions.  Should the 3' limit of a CDS (= coding
sequence) include the last nucleotide BEFORE the stop codon or the
last nucleotide OF the stop codon?  Does ORF (=open reading frame)
have the same definition?  In a small sampling of local opinions and
different sequence analysis software, there is no consensus (with
approximately a 50:50 split).  Does a rigorous definition exist?  If
not, is there a general consensus?
