What am I trying to do:

I am trying to register my functional resting state scan to the MPRAGE scan (which is saved in the freesurfer subjects directory under ‘subject_30_8_2020’ after running recon-al on a MPRAGE that was aligned to AC PC). The mgz file brain.mgz and the functional scan aligned.    

 

What are the commands I use

bbregister --s subject_30_8_2020 --mov subject_motion_corrected_func_4D_RestingState.nii --reg affine_TESTTESTTEST6July2337_1_matrix_AVERAGE.dat --init-header –bold

 

tkregisterfv --mov subject_motion_corrected_func_4D_RestingState.nii --reg affine_TESTTESTTEST6July2337_1_matrix_AVERAGEbbb.dat –surfs

 

(bbregister works, tkregisterfv does not; I only provide the bbregistercode for context)

 

What is the error?

When I try to run tkregisterfv, I get the following output:

“cd /Users/me/Documents/30_8_2020/subject_REST_CF

My platform:

macOS Mojave, version 10.14.6

 

There is no recon-al log.

 

What I tried to do/ checked:

1)   FSL is installed.

2)    the fsvglrun text describes fsvgl as a necessary file, and I found that VirtualGL is supposed to contained that, and I tried to install that. It also says that FS_ALLOW_VGLRUN should be set to 1, but I have no idea how to do that.

3)    make sure to reboot after every potential solution.

None of that worked/ resolved the issue.
