I am performing a gene annotation on an assembly and, for a specific loci, I have the following support:

Why this is not annotated as a gene by maker?

EDITED:

In maker_opts.ctl I have:

Could you show us the maker_opts.ctl file please ?

I have edited my post with the content of maker_opts.ctl.

Do you have any Maker result un your output ? Did the Maker run finish correctly ? You could load the différent tracks (est2genome, protein2genome, snap) in a genome browser. It often helps to understand.

It looks like the gene model synthesis didn't work properly. You should relaunch using the option -t 10 to be sure that everything went well. (Keep everything as it is in your folder when you re-run Maker).

I am facing similar problem. How did you solve yours? I would be grateful if you could share the solution. Thanks.
