Dear Qing Lu,

     Now that several suggestions, both ccp4 and non-ccp4, have been made,
may I suggest that you (also) try autoSHARP, available free of charge at 

                    http://www.globalphasing.com/sharp/

It includes the invocation of SHELXD to solve the substructure, and takes
you all the way to autobuilding with ARP/wARP if you have it installed and
your data resolution is sufficient. It has been around for quite a while and
has many happy users.


     With best wishes,
     
          Gerard.
