Windows Subsystem for Linux
Windows Subsystem for Linux (WSL) is an environment native to Windows 10 that allows users to have full access to a Linux based operating system via terminal without an external virtual machine. Because it is native to Windows 10, some benefits include; full access to the system's resources without user allocation, lower overhead than traditional virtual machines, and it doesn't crash (fingers crossed).
This is -not- recommended for anyone with any blue or green color blindness as any and all attempts at changing blue and green text has been met with abject failure.
Setting up Windows Subsystem for Linux 2
The source instructions are found on the Windows website and should be referenced if any problems should arise, featured here is a condensed version of those instructions.
- Run powershell as an administrator and run the following commands:
dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart
dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart
- Restart your computer.
- Run powershell again and run the following command:
systeminfo | find "System Type"
- If the terminal says you have an "x64-based PC" download and run this Linux kernel
- Otherwise, if the terminal says you have an "ARM64-based PC" download and run this Linux kernel
- Run powershell one more time and run the following command:
wsl --set-default-version 2
- Now download this Ubuntu package and run it.
- Follow the onscreen prompts to setup the Ubuntu package
Changing the background color
At this point, the text is probably an unreadable shade of dark blue and neon green on a black background. I have yet to find a solution to the text color, and I'm worried about going further as the next step would be to change system files. I don't mind (and have) destroyed virtual machines, but potential irreparable changes to my operating system is where I draw the line.
To change the background color:
- Right click on the title bar and go to "Properties"
- Go to the section labeled "Terminal"
- Checkmark the box labeled "Use Separate Background"
- Play around with various numbers in the "Red", "Green", and "Blue" boxes, I find 75 in each box to be tolerable.
Setting up FreeSurfer with Windows Subsystem for Linux 2
Onto the main event!
- Go to the FreeSurfer Download page and save the CentOS 7 x86.64 (64b) tar archive onto your C: or D: drive. (Be sure it is readily accessible.)
- Open your Ubuntu distribution and navigate to the root directory
cd ~/../../
In the root directory exists a folder named "mnt." This folder is a direct access to all files located on your various drives (C: D: E: etc.).
- Navigate to where you saved the CentOS file and move it to /usr/local. In my case;
mv freesurfer-linux-centos7_x86_64-7.1.1.tar.gz /usr/local - Go to /usr/local and type the following command
tar -zxvpf freesurfer-linux-centos7_x86_64-7.1.1.tar.gz
- Change your .bashrc file according to the instructions listed on the New Research Staff page.
- Restart your Ubuntu, if everything works you should see the following on the first line of the terminal
-------- freesurfer-linux-centos7_x86_64-7.1.1-(some numbers)-(some numbers and letters) --------
Setting up a GUI for Windows Subsystem for Linux 2
Windows has not come out with their own GUI for WSL 2 at the time of writing this. They have claimed it will be coming soon, so this step will not be of use if it is already out. To check, try running freeview in the terminal. If no GUI exists, the terminal will hang. To fix that, press Ctrl+C.
To run an external GUI:
- Download and run this file
- After installation, run XLaunch
- Display settings are personal preference, feel free to play with these
- Select "Start no client"
- Check the "Disable Access Control" box and leave the rest of the settings as is.
- If you're happy with the display settings, click "Save configuration." Save this file in a readily accessible place, as this is how you will start the GUI.
Potential Issues:
I ran into this issue when attempting to run freeview. In short, some package does not exist on the linux distribution that FreeSurfer needs. Type the following commands:
sudo apt-get update
sudo apt-get install libgomp1
