Symmetry transformation in crystal structure



To whom it may concern,
 The crystallographic symmetry transformations in the crystal structure
 file was used to produce the crystallographically related molecules.
 What I would like to know is what kind of crystallographically related
 molecules are? Is that the dimer generated from monomer or another
 monomer molecule generated in asymmetric unit?
 Thank you in advance.
 Yours,
