[Daniel Ence]

Hi Guohong, 

What version of MAKER are you running?

Thanks,
Daniel

Only the first gene in a scaffold start with exon 0. If the first gene has 3 exons (0-2), then the second gene will start from exon 3 (an example is shown below). It seems many people would prefer that in each gene, the first exon be exon 1. Is it possible to make such a change?  Thanks.
