I uploaded the datasets to the ftp site, does anyone have further advice regarding this issue?
Both datasets are for the same subject for a longitudinal concussion study and fail for different reasons.
matt1 - has "ERROR: GetDICOMInfo(): dcmGetDWIParams() 7 errors" and fails with "CORRECTING DEFECT 51 (vertices=28380, convex hull=5261, v0=32826) XL defect detected..." never completing.
matt2 - is leaving out large sections of brain despite various wsthresh adjustments (see thread below)
I appreciate any assistance you can provide.
All the best,
-Matt
Hi Matt
no idea what that would happen. If you upload the dataset we will take a look

Following your advice below, it was clearly apparent that the output from the skull stripping step was missing a lot. I tried adjusting the -wsthresh flag from 50 -> 200 and it still left major parts of the brain out.
I have a good quality mri and subject with no known anatomical abnormalities.
The log file indicates "surface validation has detected possible Error"
Does this suggest a more meaningful defect in the base image or something that can be corrected via other parameters or manual editing?
Log file attached.
Thanks,

Hi Matt
check the output of the skull stripping. This error usually means that too much (everything?) has been erased and no plausible cc could be found
