Hi Lexi,
Have you updated FSLeyes within your FSL installation? In older versions,
conda can sometimes make mistakes when generating entry points for Python
applications on macOS during an update. This should be resolved in recent
versions of conda though (specifically the python.app package).
The easiest option to resolve this is probably to delete and re-install the
fslpython conda environment within your $FSLDIR. You should be able to do
this by following these steps:
1. Delete the $FSLDIR/fslpython directory:
sudo rm -r $FSLDIR/fslpython
2. Run this script to re-create the fslpython environment:
sudo $FSLDIR/etc/fslconf/fslpython_install.sh -f $FSLDIR
