Hi,
At the very beginning of the hippocampal subfields segmentation the following message window popped up:
segmentSubjectT1_autoEstimateAlveusML cannot be opened because of a problem. Check with the developer to make sure segmentSubjectT1_autoEstimateAlveusML works with this version of Mac OS X. .... etc.
I have installed Matlab runtime and also Java Runtime
Environment: Mac OSX10.7.5 the command "uname -m" outputs x86_64 FreeSurfer V6 beta release 15 Oct 2015
Cheers, Ed
