Hi, All.I have download full packages from CCP4i website and followed the installation instructions. But I can't activate Shelx CDE programs in Experimental Phasing module. Then,how can I activate this? (PS,sharp is also disable...) Note that my OS is Ubuntu 9.04. And I had installed a WinXP version of CCP4i and that can recruit ShelxCDE program. Thanks in advance.
