[phenixbb] same origin

Hi all I wanted to compare the two models from two data set. I want the MR replacement in same origin to compare their them with respect to the map and model. I tried reforigin in ccp4 , it gave me some error , that I am not aware or not clear. I did tried overlay the two model and rfree is going up. Most likely different hands, so Is there any way to compare the two model and data and modify them in Phenix either reindex or shift the model origin to same in all cases. Thought phenix.xmanip could help, not seen any option to do it command line or in the GUI. I did tried def file, but phenix.xmanip params.def , it complains me that unknown file or keyword? any help will be appreciated. Thanks ram
