Hi Carlos, Normally if you apply a B-sharpen of 220 to a 3 Å map, the new map should look really different from the original map (no matter whether you do it yourself or autosharpen does it). So best guess is that something is not happening the way you would like it to be. A suggestion: run the quick autosharpen tutorial data supplied with Phenix. Presumably it will work normally. Then tell autosharpen to blur that map to 300 A**2. This map should look something like your map (does it?). Now apply autosharpen to the blurred map. It should apply a B-sharpen of about 250 or so (does it?). And the new blurred - then - sharpened map should look good. Let me know if that doesn't work!

Dear all,
I am facing some problems with sharpening in Autosharpen. My current map is about 3.2 Å resolution, which I obtained after CTF-Refinement and Polishing in Relion. When I use Autosharpen in default parameters, it tells me that are applied an overall Bsharp applied of 220.34 and a final Biso of 87.42; but very little sharpening is done; I was unable to observe a typical helices sharpening at this value of resolution. I did some tests setting progressive Bsharp values (240; 260; 280; 300), but I am still unable to visualize a typical helices sharpening. Has anyone had problems like that? Any tips? Thanks in advance, Carlos. _______________________________________________ phenixbb mailing list [email protected] http://phenix-online.org/mailman/listinfo/phenixbb Unsubscribe: [email protected]
