Hey all I have checked everything that was mentioned here. I dont have PHENIX installed ( I am using the current version from http://diablo/ucsc.edu/~wgscott/debian/deb/ccp4/) I checked the setup file and its set to 1 Any other ideas? Next question I would like to install the newest version of REFMAC. I downloaded the file from Garib's page) I try to use the ccp4 GUI to install the file, but it doesnt like it. It says something about it being unable to read the contents. If I gunzip then tar the file i get 3 files which I am not sure what to do with. There is also a new library file Garib recommends downloading, but in any case I cannot install the 5.4 version of REFMAC and cannot find any documentation online on how to install it! Thanks again CCP4 BB!
