WebThis tutorial shows how to use the Phaser-MR GUIs to solve structures by molecular replacement, using example data included with the Phenix distribution. We recommend reading the MR overview before running these tutorials (and for adventurous users, the primary Phaser reference as well). challenger and big boyWebBecause phenix.refine (like REFMAC) by default substitutes F-calc for missing reflections when calculating 2mFo-DFc and similar map coefficients, ellipsoidal truncation will result in eliminated high-resolution reflections being replaced by F-calc in the maps. This will always make the maps look better, because they are more biased to the model! happy go fluffy light up dome tumbler
