Starting with ChimeraX 1.2.5, the ChimeraX rpms are relocatable rpms.  So, using the CentOS 8 rpm as an example, to install it to another location, you would use:

sudo rpm -i --prefix /other/location ucsf-chimerax-1.3-1.el8.x86_64.rpm

but that only works if all of the dependencies are already installed on your system.  You can see all of the dependencies with:

rpm -qpR ucsf-chimerax-1.3-1.el8.x86_64.rpm

Those dependencies should be installed with sudo dnf/yum.

An alternative to using rpm to install ChimeraX (the dependencies still need to be installed with dnf/yum), is to extract the files using rpm2cpio (in a temporary directory):

rpm2cpio ucsf-chimerax-1.3-1.el8.x86_64.rpm | cpio -id

and mv usr/libexec/UCSF-ChimeraX anywhere you want.  And then create a symbolic link to UCSF-ChimeraX/bin/ChimeraX (which is typically "chimerax").  ChimeraX won't be integrated in to the desktop menus, but it will work just fine.  Do not put UCSF-ChimeraX on your path.

Dear chimeraX users, I want to change the installation folder of chimeaX in linux (centos7.0). The default folder is user/bin however, I want to install chemeraX in the other folder because of my computer environments (the Master and Slave nodes do not share the usr/bin folder). Can I know how to change the installation folder?

Best regards Si Hoon Park
