Installing FSL

The easiest method is to download this python script. You will need to register. On the subsequent page you will download the fslinstaller.py file.

Installing on Pop_OS!

You will first need to run the following steps prior to installing FSL.

Note

The following steps were originally written here .

Warning

make sure you run a backup prior to performing this hack… just in case.

1. move your current OS information files into a temporary location:

   sudo mv /etc/os-release /etc/os-release.pop && sudo mv /etc/lsb-release /etc/lsb-release.pop
   

2. write a new os-release file:

   sudo gedit /etc/os-release
   

   copy the following into this file:

   NAME="Ubuntu"
   VERSION="20.04 LTS (Focal Fossa)"
   ID=ubuntu
   ID_LIKE=debian
   PRETTY_NAME="Ubuntu 20.04 LTS"
   VERSION_ID="20.04"
   HOME_URL="https://www.ubuntu.com/"
   SUPPORT_URL="https://help.ubuntu.com/"
   BUG_REPORT_URL="https://bugs.launchpad.net/ubuntu/"
   PRIVACY_POLICY_URL="https://www.ubuntu.com/legal/terms-and-policies/privacy-policy"
   VERSION_CODENAME=focal
   UBUNTU_CODENAME=focal
   

3. write a new lsb-release file:

   sudo gedit /etc/lsb-release
   

   copy the following into this file:

   DISTRIB_ID=Ubuntu
   DISTRIB_RELEASE=20.04
   DISTRIB_CODENAME=focal
   DISTRIB_DESCRIPTION="Ubuntu 20.04 LTS"
   

4. now run the fslinstaller.py script in the below section and return here to Step 5 to return your OS information.

5. after running the FSL install steps, remove the files you wrote:

   sudo rm /etc/os-release && sudo rm /etc/lsb-release
   

6. move the original files back:

   sudo mv /etc/os-release.pop /etc/os-release && sudo mv /etc/lsb-release.pop /etc/lsb-release
   

Linux

Run the following in a linux terminal (the install will take awhile):

python /home/*[your_username]*/Downloads/fslinstaller.py

You will also need to install the package wxpython:

pip install wxpython

If that does not work then run:

pip install -U -f https://extras.wxpython.org/wxPython4/extras/linux/gtk3/ubuntu-16.04 wxPython
