[Freesurfer] mkcontrast-sess and mkcontrast2 matlab errors

External Email - Use Caution

Hi FreeSurfer experts,

I'm trying to run mkcontrast-sess using the newest development version of freesufer from Nov 30th, 2018, and I am getting a matlab permission denied error (see mkcontrast-sess_error text file).

It seems to be happening around line 150-160 of mkcontrast2. However, when I copy the old mkcontrast-sess and mkcontrast2 scripts from freesurfer 6.0.0 (non-development version), it works fine in the development version.

The two versions in question are the stable release 6.0.0 and the development release for centos7 Nov 30th, 2018.

Any insight into why I'm getting permission denied would be really helpful. There don't seem to be any changes between the two scripts so I'm a little confused.

Thanks, Emily
