External Email - Use Caution        

Hello,

I have tried to create a text file with command lines that can be run in parallel by using trac-all -bedp -c <config file> -jobs Parallel. 
When I use this command three text files are produced named: pre.Parallel, post.Parallel, and Parallel. Should I just use Parallel as a source for command lines? What are pre.Parallel and post.Parallel for? I am attaching my Configuration file, pre.Parallel, post.Parallel, and Parallel to this message as well. 

OS: Centos 7, Freesurfer version: 7.2.0

Thank you for your help.
Kindly,
Ela
