Assuming it uses the standard phenix syntax you should be able to string together a series of residue selections connected by “or”. 

See: https://www.phenix-online.org/documentation/reference/atom_selections.html

It should also be noted that any type of OMIT map will only show “unambiguous” density for full occupancy ligands. If your ligands are partial occupancy (which you generally can’t determine a priori), be aware that you’ll be looking at a superposition of ligand density and the other (unknown) state of the crystal. 

Dear all,

 

To generate unambiguous ligand density in a number of structures we would like to omit the surrounding active site residues in the polder-map calculation. However, so far we were unable to figure out how non-consecutive residues can be selected for phenix.polder.

 

https://www.phenix-online.org/documentation/reference/atom_selections.html

 

The documentation only explains how to select ranges of residues but not how to select say 5 individual residues.

 

Is there a syntax to achieve this ?

 

Thanks for your advice,

 

Eike
