The license file (“license.txt”) is easy to get, so don’t worry if you don’t have an existing license. Just ask follow the link to fill in the form to request another one if you are setting up on a new system.
Use the Ubuntu “DEB installer” download
Before installing the freesurfer download, install the dependencies (https://surfer.nmr.mgh.harvard.edu/fswiki/BuildRequirements ) .
It is not unusual for these commands to not work as listed. So, go through these steps from a terminal (“#” is for comments):
...:~$ sudo apt-get -y update # update all installed software # Try this ~$ sudo apt-get -y install git wget tcsh xxd build-essential gfortran # If there are errors, see suggestions in terminal. For example, you might run ~$ sudo apt --fix-broken install # Then repeat install - these are copied from webpage (18 August 2023) ~$ sudo apt-get -y install git wget tcsh xxd build-essential gfortran ~$ sudo apt-get -y install libblas-dev liblapack-dev zlib1g-dev ~$ sudo apt-get -y install libxmu-dev libxmu-headers libxi-dev libxt-dev libx11-dev libglu1-mesa-dev
You can try installing with the Software Install tool, and it will report if there are more dependency problems.
To find the dependencies, go to a terminal (since the software tool does not report what dependencies are missing).
Open a terminal in Downloads and run the command line install:
~$ sudo dpkg -i freesurfer_ubuntu...._amd64.deb # Use file name of downloaded freesurfer file
Look for names of packages not installed, and install those
Example:
~$ sudo dpkg -i freesurfer_ubuntu...._amd64.deb # Use file name of downloaded freesurfer file
Look for names of packages not installed, and install those. This is a hunt. Make sure you DO NOT run apt --fix-broken install, as this will remove freesurfer (since it’s “broken” meaning not yet installed)
sudo apt-get install -y xorg-dev sudo apt-get -y install gettext sudo apt-get -y install csh
