Note: I've never submitted an assembly/genome to NCBI, so excuse if my perspective is flawed.
I'm working with Drosophila subobscura. (spring fruit fly)
I see here https://www.ncbi.nlm.nih.gov/data-hub/genome/?taxon=7241 that there are at least 2 assemblies of better quality than the only available genome (I checked checked N50 and number of scaffolds).
However, these assemblies weren't promoted to genomes.
What is required to consider them genomes?
Is it the scaffold to chromosome notation that is missing? Or also the annotations?
How would I promote the better assemblies into genomes?
And also, if I wanted to annotate one of the better assemblies, how would I proceed?
