It is defined by the HETATM record in the pdb file.

I have some small ligands in structure (acetate, sulphate, ...) and 
those are not recognised as ligand. I can imagine, it can be handy to 
skip those, when bigger more interesting things are present, but when 
they are only ligands in structure...


I guess you will have to make sure that the ligand are HETATMs in the 
pdb file. You can use of course Coot to do so:


Extensions-> Modelling-> Assign (Force) HETATMs for this Residue
