As final step, save the molecule as a new PDB file which we will call: *hpr-ensemble.pdb*
For this in the PyMOL menu select:
-File -> Save molecule...
-Select 1HDN and click on the save button
+File -> Export structure -> Export molecule...
+Select 1HDN, set states to 0 (all states), and click on the save button
Name your file *hpr-ensemble.pdb*, make sure to select *PDB* as format and note the location of the saved file
