I'm writing up some results for which we used phenix.xtriage to screen xtals for twin fraction and would like to know if there is a paper we could/should cite?

At the time this work was done we were not using the rest of the phenix suite for refinement (we are now!).

Going to the phenix FAQS (http://www.phenix-online.org/documentation/faqs.htm#anch2) it would be PHENIX: a comprehensive Python-based system for macromolecular structure solution. P. D. Adams, P. V. Afonine, G. Bunkóczi, V. B. Chen, I. W. Davis, N. Echoo ls, J. J. Headd, L.-W. Hung, G. J. Kapral, R. W. Grosse-Kunstleve, A. J. McCoy, N. W. Moriarty, R. Oeffner, R. J. Read, D. C. Richardson, J. S. Richardson, T. C. Terwilliger and P. H. Zwart. Acta Cryst. D66, 213-221 (2010). Or maybe the developers prefer you cite the CCP4 newletters listed at: http://www.phenix-online.org/documentation/xtriage.htm#anch24 Hope this helps, Folmer Fredslund
