CCP4 v7.1 Program References

Any publication arising from use of the CCP4 software suite should include both references to the specific programs used (see below) and the following reference to the CCP4 suite: M. D. Winn et al. Acta. Cryst. D67, 235-242 (2011) “Overview of the CCP4 suite and current developments” [doi:10.1107/S0907444910045749].

References to individual programs must also be included as appropriate, see the References section of the distributed documentation. Such citations are vital to the CCP4 project and individual program authors in maintaining funding and thus being able to develop CCP4 further.

Many relevant articles can be found in the proceedings of the Study Weekend, published as a special issue of Acta Cryst D.
