ccp4i -t sketch
Sketcher is an interface to the LIBCHECK, which can be used to create new monomer library descriptions for use in refinement.
The sketcher is part of the CCP4 graphical user interface ccp4i and cannot be run as a standalone application except in the fashion described in the synopsis above. More normally Sketcher is accessed from within CCP4i, via the ``Monomer Library Sketcher'' task in the ``Refinement'' module.
The full Sketcher documentation can be found at $CCP4I_TOP/help/modules/sketcher.html
