I have been running the cerebrum labeling step for several subjects, and I have been getting this warning for some of them:
Performing warp alignment (order=5) of atlas brain to subject brain
alignwarp.c: 262: WARNING: Registration terminated due to a Hessian matrix that was not positive definite
Inspection of results is advised
I get this warning in the GUI as well as the command line. Does anyone know if there’s a way to fix this issue?
