Hi All,
I am attempting to transform sets of coordinates from subject CRS space
into the surfaceRAS space of an average subject, made with
make_average_subject.
By our current method, we register the individual CT to the average surface
using mri_robust_register with the command:
mri_robust_regis
in MATLAB.

trix? Also, what coordinate system are you trying to go to?

Any other thoughts as to what might be going wrong with our coordinate
transformations / any other transformations that we might not be taking
into account?
Thanks,

Hi All,
I'm trying to reconstruct surfaces using recon-all. Though many of the
subjects have succeeded, a few are failing at the mri_nu_correct stage. The
error file (posted below) provides little detail as to why the error is
occurring.
Even if it is not fixable, it would be nice to know what cau
