External Email - Use Caution        

Hi Tim,

I'm running freesurfer on linux. And the exact error is:
ncvarput: ncid 5: Protocol error
miicv_put: MINC package entry point
nu_estimate_np_and_em: crashed while running mincmath (termination status=768)
nu_correct: crashed while running nu_estimate_np_and_em (termination status=768)
ERROR: nu_correct
Linux neurodebian 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt9-3~deb8u1 (2015-04-24) x86_64 GNU/Linux


here are the outputs for the directories.
1) /home/brain/freesurfer
2)-rwxr-xr-x 1 brain brain 20569 Jun 19  2015 /home/brain/freesurfer/mni/bin/nu_correct

Any idea?  I've tried it on several datasets and still the problem, though the example data sample-001.nii.gz doesn't throw this error.

best,
sev

Dear Sevan,

Which version of FreeSurfer are you running on which system (Mac, Linux?), and what is the exact command line and error message?

In case it is about nu_correct not being found: it should be in $FREESURFER_HOME/mni/bin/nu_correct, and if you get that error, most likely your environment variable $FREESURFER_HOME is not setup correctly for your shell.

Please also report the output of these 2 commands so we can know more:

1) echo $FREESURFER_HOME
2) ls -l $FREESURFER_HOME/mni/bin/nu_correct

Best,

Tim
