Hello FreeSurfer Developers, 

I am running FS-FAST on my mac. My freesurfer version is freesurfer-i386-apple-darwin11.4.2-stable6-20170119. My MAC version is macOS High Sierra 10.13.4 (17E202). I downloaded Matlbab Runtime on this site: http://www.freesurfer.net/fswiki/MatlabRuntime as constructed. When I run this command: { mkcontrast-sess -analysis my-language.sm05.lh -contrast language-v-base -a 1 }, I kept getting this error. 

ERROR: cannot find matlab. Is it in your path?
ERROR running mkcontrast

Then I downloaded Matlab runtime R2014a (8.3). I still got the same error as above.

Then I downloaded Matlab runtime R2018a (9.4). Still the same error. 

I assume I should download a certain version of Matlab Runtime in order to run FS-FAST on freesurfer-i386-apple-darwin11.4.2-stable6-20170119 on my macOS High Sierra 10.13.4 (17E202). 

Could you help me? Thank you.
