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
