Appreciate it. @Greg Couch, Thank you for the detailed instructions. It is awesome and good to know that the rpm is relocatable rpm which helps. Also if you have the instructions on compiling from Github source repo, could you please share it. Thank you!

(1) If you want to be able to install ChimeraX as a user, the recommendation is to use the flatpak. Your system administrator may need to install the flatpak command. That way you can update your version of ChimeraX anytime. Follow the per-user instructions in https://urldefense.com/v3/__https://www.cgl.ucsf.edu/chimerax/flatpak.html__;!!AoaiBx6H!zRFeYbRlx4jSNoz2EOjFlnDIV7g0-ofjgWJdcbAi1brd2hlsNSo_gfD73ctixOYysLwffPFz7PjjWgEnPwfFhGz0NSLQFw$<https://urldefense.com/v3/__https:/www.cgl.ucsf.edu/chimerax/flatpak.html__;!!AoaiBx6H!zRFeYbRlx4jSNoz2EOjFlnDIV7g0-ofjgWJdcbAi1brd2hlsNSo_gfD73ctixOYysLwffPFz7PjjWgEnPwfFhGz0NSLQFw$> . This works for most Linux variants. (2) The next two solutions depend on the ChimeraX dependencies being installed by the system administator. The list of dependencies is given by: rpm -qRp ucsf-chimerax-1.10.1-1.el9.x86_64.rpm There are a lot, but many are already installed. They should be installed with dnf/yum. (2a) If you want to install ChimeraX in a non-standard location, the system administrator can take advantage of the fact that the ChimeraX rpm is a relocatable rpm. So, after the dependencies are installed: sudo rpm -ivh --prefix=/path/to/non/default/dir ucsf-chimerax-1.10.1-1.el9.x86_64.rpm That rpm command will tell you what dependencies are missing, so you can iteratively install the missing dependencies instead of installing all dependencies. (2b) If you want to install ChimeraX as a user by extracting the files from the rpm, then after the dependencies are installed: rpm2cpio /path/to/ucsf-chimerax-1.10.1-1.el9.x86_64.rpm | cpio -idm Use the bin/chimerax symbolic link to start ChimeraX. That is, do not put the libexec/UCSF-ChimeraX/bin directory on your PATH.

Would it be possible to provide the pre-built tar package of the latest version for Redhat 9. With the previous version we were able to download the pre-build tar package from your website (example: ChimeraX-0.93.tar.gz), but now I see there is only .rpm package (https://urldefense.com/v3/__https://www.rbvi.ucsf.edu/chimerax/download.html__;!!AoaiBx6H!zRFeYbRlx4jSNoz2EOjFlnDIV7g0-ofjgWJdcbAi1brd2hlsNSo_gfD73ctixOYysLwffPFz7PjjWgEnPwfFhGzGpS9NZw$<https://urldefense.com/v3/__https:/www.rbvi.ucsf.edu/chimerax/download.html__;!!AoaiBx6H!zRFeYbRlx4jSNoz2EOjFlnDIV7g0-ofjgWJdcbAi1brd2hlsNSo_gfD73ctixOYysLwffPFz7PjjWgEnPwfFhGzGpS9NZw$> ) which will need to be installed in the OS level. I was looking to get a pre-build tar file for the latest version so we can install it without having to do the rpm install. I am aware there is github source for ChimeraX where we can build but would greatly appreciate if you could provide tar installer. Thank you! $ cat /etc/redhat-release Red Hat Enterprise Linux release 9.4 (Plow) Best Regards, Charitha Shetty Hello Charitha Shetty, ChimeraX usage & support questions should be sent to chimerax-users@cgl.ucsf.edu<mailto:chimerax-users@cgl.ucsf.edu> <mailto:chimerax-users@cgl.ucsf.edu> (without any data that should be kept private) since the commercial licensing team cannot answer that type of thing. I've CCd that address so you don't need to send your question again. I don't see that as an option on our download page, so my guess is probably not, but we can see if others on the list respond.
