Correct. Current MAKER 2.31.9 AND 3.00 beta have the strict codon table workaround for BioPerl.

MAKER’s default behavior is to use the same ORF given to it be the predictor and alter start codon if MAKER itself is able to add extra sequence that can extend the ORF during the UTR addition phase and find a start codon. But if you set alway_complete=1 in the options, it will walk upstream and downstream to find start/stop codons in the surrounding sequence even if it has to add sequence to the exons.

Thanks,
Carson
