I installed open-source pymol software using miniconda4 which have been installed successfully. I worked with the software, but whenever I am shutting down my PC and again restarted, the >pymol command on miniconda4 to open Pymol is not working. It is neither showing error nor opening. When I am trying to reinstall it, it is showing pymol is installed in my computer, and suggesting to reinstalled. It happened more than once. Now I am in a situation, whenever I am needing this software, I am installing it afresh or cannot shut down my PC. Can anyone shed some light on this problem and how to work on it?

    $\begingroup$ The installation via conda only is one of the options. Did you try the installation via the package manager of your distribution (example Debian's tracker), or the images published here? In case you use Windows as OS, hovering over the .zip archive reads «unzip and run PyMOLWin.exe -- that simple!» like about a portable executable that will not nest into the PATH variable; would this be an option for you? $\endgroup$

    $\begingroup$ Do you use environments with conda? The executable will be accessible only in the environment where there were installed. Also, try to manually add the installation folder to the system path. $\endgroup$

  • $\begingroup$ To illustrate @Camps' comment about environments, compare the pattern used e.g., for the installation and use of RDKit with conda (outlined, e.g., in RDKit's documentation). $\endgroup$

  • $\begingroup$ It might be helpful to include the details like OS and with what shell you are typing the pymol command in. If you are using linux, which pymol should give you the path where pymol is installed and in normal circumstances if it can't find it, there should be an error. $\endgroup$ Commented Dec 23, 2021 at 11:37
