Hi, I have installed ccp4 and phenix on ubuntu 14.04 LTS. When I open coot while using phenix or ccp4 and try to load a molecule from a Search Monomer library, it is unable to load the molecule and this pop up " You need to setup CCP4 (Specifically LIBCHECK) first. I will appreciate if someone can guide through this.
