​Hello Freesurfer developers, 

I was running FSFAST preprocessing​:

preproc-sess -s
​[subject] 
-fsd bold -stc up -surface fsaverage lhrh -mni305 -fwhm 0 -per-run

​The process finished without errors. However, the ​register.dof6.dat is missing from the subject's folder. I could not find any error in the ​register.dof6.dat.log file (see attached).

- Freesurfer version: freesurfer-Linux-centos6_x86_64-stable-pub-v6.0.0-2beb96c
- OS: Ubuntu 16.04 LTS
- recon-all.log file is also attached.

Thanks!
Guy
