Hi Benjamin,

Thanks for trying to help me.
Apparently reassigning the wfu file to the matlab path again made it work.



Thanks again,

Just for information, this is what was written in the matlab command window when trying to save a VOI.

ans =
atlasname: 'HUMAN ATLAS'
subdir: 'MNI_atlas_templates'
lookupfile: 'master_lookup.txt'
dispimage: 'MNI_T1.nii'
licensefile: 'info.html'
conversionfile: 'atlas_space_conversions.txt'
conversion: [1x2 struct]
