Hello FreeSurfer community, I am running into a problem with my longitudinal data in the new FS5.1 and am wondering if anyone else has run into this error message during the unbiased template creation. I have 4 scans from 2 subjects and have run into the same error at the same place. I only run into this problem when I try running the analysis on all 4 scans - it has completed without error whenever I have tried different combinations of 2 or 3 scans so I don't think it is a problem with my data.
The unbiased template creation gets to the point of Registration:computeMultiresRegistration and completes TP 1 and 2. When it gets to TP 3, it runs fine until it starts calculating Resolution: 0 S(256 256 256 ) T (256 256 256) On Iteration(f):2 I get the message "Killed".
Since there isn't much info in the error message I'm having trouble figuring out what to troubleshoot next. As I mentioned above, I get this error message in 2 subjects in exactly the same place and the process completes without error when I use separate combinations so I don't think it's a data problem. And since 3 time points have run successfully I don't think that it is an issue of not having enough computer resources..... I am running freesurfer in a Oracle virtual box on a windows 64 bit computer.
Any suggestions would be greatly appreciated.
Cheers,
