Dear experts,

We are running longitudinal pipeline for bunch of our MS subjects. Longitudinal recon-all failed to create volumes and surfaces for few of our subjects. We ran cross-sectional and did all the edits on them and after that ran base script without any issues or errors. When we run longitudinal on them it runs recon-all fine without exiting with errors. However it did not create important surfaces and volumes. Please find attached log file for one of the longitudinal timepoints for details. 

Not sure why did they fail only for few of them as we have ran 100s of them with no issue earlier. Any advice will be of great help!

Thanks,

Sneha
