Translation when circular genome and ORF in the cut of the assembly

[BenjaminGuinet]

Hello I have a gff3 file such as :

1   Geneious        CDS     101     10548   .       +       0       Name=1_ORF104;product=hypothetical protein
1   Geneious        gene    101     10548   .       +       0       Name=1_ORF104;product=hypothetical protein

This is part of a circular viral genome, how can I code the gff3 file to get the translation from 100548..101121 and 101121,1..101 using --translate in EMBLmyGFF3

instead of the translation of the protein from 101 to 10548

such as :

complement(join(100548..101121,1..101))

Thanks for your help

You must use the qualifier ribosomal_slippage in the CDS feature: https://www.ebi.ac.uk/ena/WebFeat/
So it will be a ribosomal_slippage attribute of the CDS feature in the GFF.
But I think the mechanism to automatically reflect this information in the EMBL file by EMBLmyGFF3 is not implemented (it will be among the qualifiers but the join operator will not be inserted).
