The log file looks like it has everything you have run, but I don't see an error at the bottom. Maybe it is in there somewhere, but you will need to extract it for me. When DOF=0 means that you have more regressors than time points. This can sometimes happen when you accidentally include a terminated run in the analysis (so there are many fewer time points than expected).

External Email - Use Caution
Hello Freesurfer Developers,
I am currently running the fs-FAST preprocessing command, and this is a frequent error that I keep running into across various datasets of ours.
DOF = 0
I have searched the listserv in order to find any possible solutions for my query, but to no avail. Another curious issue that comes up is when I re-run the preproc-sess command after the above error, it proceeds without issue and completes the process, which has further confused me as to what the possible issue could be.
Attached is the terminal session output for you to take a look at.
Thank you so much for all your help!
Best, Hibah
