Dear ChimeraX Team, The install notes for all the current distributions for the Linx system require sudo. I wonder is it possible without sudo? On Rocky Linux VERSION 9.4 (Blue Onyx), I tried the following. $ flatpak --user install ChimeraX-1.8.flatpak error: The application edu.ucsf.rbvi.ChimeraX/x86_64/master requires the runtime org.freedesktop.Platform/x86_64/23.08 which was not found $ rpm -ivh ucsf-chimerax-1.8-1.el9.x86_64.rpm error: Failed dependencies: fftw-libs-single is needed by ucsf-chimerax-1.8-1.el9.x86_64 mesa-libOSMesa is needed by ucsf-chimerax-1.8-1.el9.x86_64 sqlite is needed by ucsf-chimerax-1.8-1.el9.x86_64 xcb-util-cursor is needed by ucsf-chimerax-1.8-1.el9.x86_64 xcb-util-image is needed by ucsf-chimerax-1.8-1.el9.x86_64 xcb-util-keysyms is needed by ucsf-chimerax-1.8-1.el9.x86_64 xcb-util-renderutil is needed by ucsf-chimerax-1.8-1.el9.x86_64 xcb-util-wm is needed by ucsf-chimerax-1.8-1.el9.x86_64 Thanks, Roden -- This message and its contents, including attachments are intended solely for the original recipient.
