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​
