[phenixbb] Phaser

Hi all !!! Is it possible to fix one domain and search for the second one in phaser !!! What are the keywords to use for that. I have a protein with two domains. It i give both the domains together it is not finding the solution. If i give only one domain it is giving the solution and the R and Rfee is 28 and 33. But it is not finding the second one. Thanks in advance for your suggestions.. regards John
