This is somewhat strange, but, under Utilities I can only see the Volume Tools and cannot find the Sharpening Tools.
I am running the latest version of cryoSPARC 2.2 (it was missing also in an earlier version of cryoSPARC 2).
Hi, I got the sharpening tools to appear after restarting the computer. It may also be that killing all cryosparc related processes would work. Only updating did not restart the webapp completely (or some other process), which prevented the updates from appearing in the browser.
