Hi Elaine, 

Thanks a lot for the reply. I was aware of the filtering, but constraining the search would be more efficient. If this could be implemented in a future release of ChimeraX, I believe it would be useful for many :) 

Thanks a lot and best wishes, 
Matthias

Hi Matthias,
There is no option to restrict the search itself.  However, when you get the results back, you can show the "Species" column and (optionally) sort the results by that.  See screenshot attached.
I hope this helps,
Elaine

This would facilitate identifying homologs in your favorite model organism, rather than picking up the most closely related homolog overall (i.e when using the alphafold database).
