Hi, If there is a hinge motion between the two domains, then allowing for this will give you a much better starting model. As Klaus suggested, you may just be able to do rigid body refinement of the two domains. However, it is also possible to place the two domains separately in Phaser, by

Dear All, The density obtained after molecular replacement using phaser at 2.5 Angstrom and then used buccneer for autobuilding of the model. I am not getting reasonable R value (it is 38.5 %) but the figure of merit is 0.629. As My protein has two domains. So is it possible to fragment the

Dear Prem, If your protein has 2 domains, it is possible that they their relative orientation is different in your target compared to the search model. Therefore searching with the two domains separately can improve your Z-score in Phaser and give you a better map. However, you did not tell
