[Freesurfer] mri_robust_register

Hi gurus, The output of mri_robust_register includes some instruction for checking the registration.

In my case the ouput said I could check the registration by running "tkregister2 --mov 0110837_20090425/mri/001.anatomicalspace.mgz --targ 0311501_scan1_20061205/mri/001.anatomicalspace.mgz --lta 0110837_20090425/mri/transforms/robustreg.lta --reg 0110837_20090425/mri/transforms/robustreg.reg"

However, when I run this I get the error that file 0110837_20090425/mri/transforms/robustreg.reg does not exist. Mri_robust_register appears to exit without error and creates the linear transform array file, but it did not create a file called robustreg.reg. Did something go wrong?
