you can also use the python equivalent so you're not trying to run mex
files

The .mexa64 file is a matlab shared library and that error is from
the linker saying it is not allowed to link in that library. Note that
it did not say there was a permission denied error or that the .mexa64
file could not be found. This Mathworks posting indicates that error
can happen on systems when SElinux security is enabled,

This part of LD_LIBRARY_PATH looks like the standard setting after
running fs_install_mcr script with the Matlab runtime environment
installed in the freesurfer distribution. I'm assuming accessing
MALAB runtime environment this way is already known to work on your
cluster and does not generate any run time linker errors.
LD_LIBRARY_PATH is
.:/usr/local/freesurfer/7.1.1//MCRv84//runtime/glnxa64:/usr/local/freesurfer/7.1.1//MCRv84//bin/glnxa64:/usr/local/freesurfer/7.1.1//MCRv84//sys/os/glnxa64:/usr/local/freesurfer/7.1.1//MCRv84//sys/java/jre/glnxa64/jre/lib/amd64/native_threads:/usr/local/freesurfer/7.1.1//MCRv84//sys/java/jre/glnxa64/jre/lib/amd64/server:/usr/local/freesurfer/7.1.1//MCRv84//sys/java/jre/glnxa64/jre/lib/amd64/client:/usr/local/freesurfer/7.1.1//MCRv84//sys/java/jre/glnxa64/jre/lib/amd64:/usr/local/freesurfer/7.1.1//lib/vtk/lib
- but the path to that .mexa64 file is not part of the standard
LD_LIBRARY_PATH settings and looks like it is on some temporary mount
point,
/tmp/MCR_65032579/.mcrCache8.4/segmen0/autofs/space/panamint_005/users/iglesias/software/freesurfer.GEMS2.terrier/bin/kvlGEMSMatlab.mexa64':
/tmp/MCR_65032579/.mcrCache8.4/segmen0/autofs/space/panamint_005/users/iglesias/software/freesurfer.GEMS2.terrier/bin/kvlGEMSMatlab.mexa64
- so I'm guessing there is some system and/or security setting that
does not allow loading 3rd party libraries from paths like that. I
would ask your IT folks about it. I could be wrong, but if
kvlGEMSMatlab.mexa64 needed to be re-compiled to run on your system,
then I would expect to see a different error.
