The coordinates of the ligand were modified in the PDB file, using a
text editor.
As in, how does one not let modeller choose the
default restraints from the template
Modeller automatically restrains certain distances to resemble the
template, so that ligands end up in the right place. See
http://salilab.org/modeller/9.12/manual/node70.htmlThe last entry in the list on that page is the important one here -
ligands are restrained to stay near protein CA atoms. By moving the
ligand away, those restraints won't be added. Instead, the manually
added ligand-CA restraints will be (and these will pull the ligand back
into the correct position during modeling).
