[maker-devel] duplicate CDS in annotation

Dear Carson,

The new version does indeed fix the problem!

However, I noticed that some of the CDS annotations were swallowed. This
seems to affect a ~600 genes.

e.g. input:

pbar_scf7180000349951 maker mRNA 98033 98530 . - .
ID=PB12301-RA;Parent=PB12301;Name=PB12301-RA;Alias=maker-pbar_scf7180000349951-snap-gene-1.17-mRNA-1;_AED=1.00;_QI=0|0|0|0|0|0|2|0|81;
pbar_scf7180000349951 maker exon 98393 98530 . - .
ID=PB12301-RA:exon:10283;Parent=PB12301-RA;
pbar_scf7180000349951 maker exon 98033 98140 . - .
ID=PB12301-RA:exon:10284;Parent=PB12301-RA;
pbar_scf7180000349951 maker CDS 98033 98140 . - 0
ID=PB12301-RA:cds:10114;Parent=PB12301-RA;
pbar_scf7180000349951 maker CDS 98393 98530 . - 0
ID=PB12301-RA:cds:10113;Parent=PB12301-RA;

output:

pbar_scf7180000349951 maker mRNA 98033 98530 . - .
ID=PB12301-RA;Parent=PB12301;Name=PB12301-RA;_AED=0.38;_eAED=0.38;_QI=0|0|0.33|1|0.5|1|3|246|165;Alias=genemark-pbar_scf7180000349951-abinit-gene-1.14-mRNA-1,PB12301-RA

Thank you,
