You run them in that order. First the pre, then the parallel, then the post. You can queue them that way, so that the parallel jobs wait for the pre to finish, and the post waits for all the parallel jobs to finish.

Subject: [Freesurfer] TRACULA -bedp parallel processing

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
