External Email - Use Caution

Sorry, that fix did not infact fix the problem. I am still getting the following error.

Sorry, the beginning of the email seems to have been cut off. I was trying to run trac-all on one of my subjects to troubleshoot running the following command.

trac-all -prep -c /Volumes/DANIEL/dmrirc.long.example.single.sh

I posted the errors and attached the dmrirc file I used below.

There seems to be an issue with

The error does not seem to be due to dwi_orig.nii.gz being missing as I see it in the folderr after it has been written there in a previous command.

What could be leading to these issues?

Hello,

trac-all -prep -c /Volumes/DANIEL/dmrirc.long.example.single.sh with the attached configuration file.

I get the following error message
