I would like to add a directory to my path, in my IBM server running Ubuntu 22.04. I would like to install the genome assembly software, SuperNova-2.1.1 by 10x genomics. In order to start using their supernova command, I must add the directory to my path. The path was added using the following command:

export PATH=/opt/supernova-2.1.1:$PATH

They have also suggested adding the path to .bashrc, which I don't know how to perform. Anyways, the problem is when I try to invoke their supernova command, the prompt says command 'supernova' not found. Can someone help me understand the problem, and how to add the command to the .bashrc?

NB: The details on how to navigate through the installation can be found here.

  • *"adding the path to .bashrc, which I don't know how to perform"* you just open the file in any text editor, and type your changes - see for example [Permanent PATH variable](https://askubuntu.com/a/500794/178692) – steeldriver Feb 21 '23 at 12:04
  • Welcome to Ask Ubuntu! Does it work if you run `/opt/supernova-2.1.1/supernova`? If not, then it isn't installed properly, and adding it to the path isn't going to help. – NotTheDr01ds Feb 21 '23 at 15:54

    Also a question - You have this tagged [tag:windows-subsystem-for-linux], but you mention that you are running Ubuntu on your "IBM server". This doesn't quite match up. WSL is a Microsoft feature for running Ubuntu under *Windows*, not on an IBM server. It probably doesn't matter for this question, but you may want to clarify or remove the WSL tag. Thanks! – NotTheDr01ds Feb 21 '23 at 15:55
  • Thanks for the response. Actually, the problem was resolved by invoking the supernova command as follows: ./supernova – VIJITH KUMAR Feb 22 '23 at 07:09
