Hi Tom, thank so much you for your answer. I uploaded the nigthtly build and it worked far better (a couple of hours) and ended correctly. I noticed that the gain was due to the fact the only about 2400 boxes were calculated (in place of more than 40000 in my slow previous calculation, likely explaining the gain of a factor 20). As i have a very large map, i wonder how this affects the quality of the LocalResolutionMap. And i also wonder if there is a mean to define this parameter to study this effect. Thank you so much for your help. Best regards. Philippe. ----------------------------------------------- Philippe Cuniasse, PhD/HDR. Institut de Biologie Integrative de la cellule.

If you download a nightly build like this one: https://phenix-online.org/download/phenix/nightly/?version=1.21rc1-5130 then it should be a lot faster (still not quick, but in your case should be 20x faster).

I run it on my MacBook pro (M1 running OSX 13.4 with 32Gb RAM) on 4 cpu. The calculation actually runs on 4 CPUs.

Hi Tom, Thank you so much. I will test some values of this n_boxes parameter. Best regards. Philippe. ________________________________ De : Tom Terwilliger Envoyé : dimanche 29 octobre 2023 14:03:45 À : CUNIASSE Philippe Cc : [email protected]; Tom Terwilliger Objet : Re: [phenixbb] Pb LocalResolutionMap calculation Hi Philippe, Yes, certainly the number of boxes affects the resulting local_resolution map. The 2400 boxes correspond to 14x14x14 boxes for a cubic map which means that you have only a gradual sampling along any axis of your map. You can adjust the number of boxes with the parameter n_boxes=2400. In the GUI, search under "All parameters" for "box" and you'll get the entry form. I will move this to the front page in tomorrow's nightly build of Phenix so it is easier to set.
