Qdec, as well as tksurfer and tkmedit, are no longer supported on mac OS 10.15+ since they are 32-bit binaries. These programs are also no longer maintained in our development distribution, so you will have to use a different OS or move to a command line analysis.

External Email - Use Caution

Dear Ladies and Gentlemen,

I am trying to run „Qdec“ which worked pretty well until I installed the new version of macOS Catalina (version 10.15.1). Since then, I always receive an error called "Bad CPU type in executable“. I am working with Freesurfer version 6. Is there anything I can do about it?

Thank you for your support.

Yours sincerely
