[phenixbb] Problems with sharpening in Autosharpen

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.
