Dear Prof Greve

I am  having an issue running reg-feat2anat and I get the following error

Initializing exf2anat with header

tkregister2_cmdl_cmdl --targ /Applications/freesurfer/7.1.1/subjects/sub1/mri/brainmask.mgz --mov BLOCK1_LEFT.feat/example_func.nii.gz --reg BLOCK1_LEFT.feat/reg/freesurfer/anat2exf.register.dat.init --fslregout BLOCK1_LEFT.feat/reg/freesurfer/exf2anat.init.fsl.mat --regheader --noedit

tkregister2_cmdl_cmdl: Command not found.

I saw your answer in

I was not able to download the link because it requires an user and password.

Could you help me with this issue 

Thank you
