Re: [phenixbb] Labeling centric and acentric reflections

Hi Andre, ok, done! Any next version after dev-4822 will have it. Just run like phenix.reciprocal_space_arrays data.mtz model.pdb and output MTZ file will have CENTRIC_FLAGS array. https://phenix-online.org/download/nightly_builds.cgi?show_all=1 Pavel On 12/22/22 05:38, Andre LB Ambrosio wrote:

Dear Pavel, thank you for your kind reply. Yes, some of my students are familiar with using CCTBX and will try now the access the centric_flags method. However, if you think that it could also be incorporated into phenix.reciprocal_space_arrays, to be used in the upcoming downloaded versions of Phenix, it would be greatly appreciated. With best regards, Andre.

I'm not aware of Phenix tool to do this. However, if you use CCTBX then you can access these flags as as a method of miller array class (called "centric_flags").

I can help with the script if interested.

Alternatively, I can extend this quite old command line program: phenix.reciprocal_space_arrays -- it outputs lots of this kind of technical arrays but just not the centric/acentric flag, but I can add it.
