Good Morning Experts,

I am having trouble checking the registration per step 2 of the pet surfer tutorial: http://freesurfer.net/fswiki/PetSurfer. The line:

mri_coreg --s subject --mov template.nii.gz --reg template.reg.lta

worked just fine but when checking the registration using the line:

tkregisterfv --mov template.nii.gz --reg template.reg.lta --surfs

I get the following output:

set: Variable name must begin with a letter

Any advice as to how to resolve this issue will be greatly appreciated.

Thanks,

Anderson Napolitano
