External Email - Use Caution

Hello Wafaa,

I believe qdec runs as a 32 bit application.  You may see Mac OS 10.14 put up a window warning that an application is not optimized for the system and needs to be re-compiled by its developer; that means it is a 32 bit app.  While many 32 bit apps that ran on High Sierra (10.13) run on Mojave (10.14), I don't think it is guaranteed they will run OK on 10.14, e.g., qdec trying to use 32 bit floats while Mac OS 10.14 is expecting apps to use 64 bit floats.  I do know that 32 bit apps will not run at all on the next rev of Mac OS that was just announced, Catalina, Mac OS 10.15.

 I don't know if there is a 64 bit version of qdec.

Hello all,

I have been using freesurfer-Darwin-OSX-stable-pub-v6.0.0-2beb96c on macos high sierra, then I updated to mojave 10.14. freeusrfer was working all good for a while. BUT, for unknown reasons, I am no longer able to overlay the significance maps using tksurfer and cant open qdec, like below:

command: tksurfer fsaverage lh inflated

output error:

I reinstalled freesurfer again and I still get the same errors. Freeview works just fine. Any input of how to solve this issue? 

Thanks in advance, 

Wafaa
