Hi,

I have a gff file of a genome that I obtained from NCBI. The gff file and corresponding genome fasta come from a recently published paper in Nature. However, the gff file only contains one type of feature, i.e. "genomic DNA". I don't receive any hits when I grep for gene or CDS etc. Why would the gff file only contain one feature?

My goal was to extract all CDS from the protein-coding genes in the genome fasta with the help of the gff file, but how am I suppose to do this if my gff file doesn't even contain the coordinates I need for CDS? Can someone elaborate, I am confused.

Thank you!
