[Freesurfer] recon-all exits after mri_nu_correct

2014-07-15 Thread ISAAC PEDISICH
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

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, Isaac On Tue, Apr 29, 2014 at 4:52 PM, ISAAC PEDISICH i...@sas.upenn.edu wrote: The purpose of what I'm trying to do is getting

, what coordinate system are you trying to go to? The equation you have below takes CRS in the CT and maps it to tkrRAS in the anatomical. If you want to map the CRS in the anat then use inv(Tanat) * inv(Reg_avg) * Tmov * CT_coords On 04/28/2014 03:58 PM, ISAAC PEDISICH wrote: Hi Doug, Thanks
