External Email - Use Caution If you have not already done so, I would try installing and running a version of the Matlab runtime environment (which is not a full blown Matlab installation) that freesurfer was tested with. For the 7.4.1 freesurfer release, that should be R2019b. (Prior to that, it was R2014b - which you could try as well - but that would likely contain an even older version of glibc). Assuming that you can write to your own installed version of freesurfer, then once you have set FREESURFER_HOME, you can try running the fs_install_mcr script included with the freesurfer distribution. See bash shell commands below. - R.
$ export FREESURFER_HOME=<your install path> $ cd $FREESURFER_HOME/bin $ sudo FREESURFER_HOME=$FREESURFER_HOME ./fs_install_mcr R2019b … answer y to any installer questions ... Then I think it should work to find the Matlab libraries by at least start off with setting, $ export LD_LIBRARY_PATH=$FREESURFER_HOME/MCRv97/bin/glnxa64 Please make sure you have otherwise removed any references to your previous matlab 2020a environment from PATH, LD_LIBRARY_PATH, etc. - R.
