I recall being frowned upon by my former supervisor (a small molecule crystallographer) for having crystals larger than the beam and for looking at fishnets .... In any case, xtriage will detwin data with anomalous signal properly. download the latest version from www.phenix-online.org (either cci_apps or the latest phenix development release) Note that according to Dauter (sorry, i forgot the reference), finding a substructure in twinned data is usually not a problem (given reasonable data). Improvement on the density modification according to Dauter can be obtained by performing density modification on detwinned data. HTH Peter
