Hi, Is there a way to label centric and acentric reflections in the .mtz file and output an additional column, let's say, with values 0 (acentric) and 1 (centric), similar to R_free flags? Many thanks for your attention. -- Andre LB Ambrosio Associate Professor, IFSC/USP - Brazil www.ifsc.usp.br/alba
Hi Andre,

Many thanks for your attention.
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.

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.

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:
