CCP4 ---- The `CCP4 `_ (Collaborative Computational Project Number 4) program suite provides an integrated suite of programs for determination of macromolecular structures by X-ray crystallography. The ccp4i2 GUI can be accessed via the Open OnDemand Applications. CCP4 is made available on the cluster as a shared :doc:`Apptainer ` container image. To run CCP4 binaries within the container, prefix any command with the name of the apptainer image, :code:`ccp4.sif`. Alternatively you can enter an interactive shell in the container with: .. code-block:: bash ccp4.sif /bin/bash via SBGrid ^^^^^^^^^^ See :doc:`SBGrid `
