It looks like starting with Freesurfer v7.0.0, bias field correction is done with ANTS N4 instead of the MINC software. ANTS installation apparently is also not required. Would it make a difference if I re-ran recon-all after installing minc toolkit binaries? I'm going to go ahead and rerun it again for now.

You can re-run it. Send the recon-all.log if you still have problems.

Hi Yujing,
My recon-all just ended at that point. It didn't make it through the entire processing stream. Should I rerun the entire process or make any additional adjustments when I submit my script again?
Sincerely,
Yilei

It looks like Freesurfer can’t find minc toolkit binaries on your system.
Did your recon-all finish fine? I think FS 7.2 recon-all is configured to use ANTS N4BiasFieldCorrection for nu correct by default.
This is from your log:
“mri_nu_correct.mni --no-rescale --i orig.mgz --o orig_nu.mgz --ants-n4 --n 1 --proto-iters 1000 --distance 50”
Best,
Yujing

Hi Freesurfer support,
Recently, I submitted a script to run recon-all on 100 mri images on UCSD's computing cluster, called EXPANSE. I get an error file that says "nu_correct: Command not found. FREESURFER: Undefined variable." The sample error file and the output file I have attached for one of the subjects are recon-all-slurm.29376886.exp-5-44.err & recon-all-slurm.29376886.exp-5-44.out respectively. The script I used to submit the job via slurm is called recon-all-slurm.sb.
I googled the error and found that someone else who had a similar situation did not source their Freesurfer environment correctly. Would this be the same thing for us as well? The main thing for us is Freesurfer/7.2.0 already has been available as a module for us on EXPANSE.
Sincerely,
Yilei
