[chimerax-users] Fourier transform tool in chimeraX?

Dear ChimeraX community, I stumbled upon a link<https://www.cgl.ucsf.edu/chimera/data/downloads/1.2470/docs/ContributedSoftw...> discussing a Fourier Transform tool in Chimera. However, I encountered an issue while trying to locate it in my Chimera version (running the command "start Fourier Transform" resulted in an error). My objective is to generate a Fourier space diffraction pattern of a helical reconstructed volume by performing its Fourier transform. I am curious to know if this functionality is available in either Chimera or ChimeraX. Could you kindly provide some guidance on this matter? Thank you in advance for any advice. Abhi
