Hello, If you have Phenix, try phenix.find_ncs (sorry for the non-CCP4 answer).
The example run in the PHENIX documentation is: phenix.find_ncs anb.pdb mlt.mtz This will then write out the NCS operators in various flavours. Basically if you have a list of Se sites it calls RESOLVE, but has a simpler, command-line interface. http://www.phenix-online.org/documentation/find_ncs.htm#anch20 Good luck, Mark On 20 May 2010 23:47, Karin van Straaten <kev...@mail.usask.ca> wrote: > > Dear all, > > Does anyone know if NCSFIND is still available or how I can get it.
