Dear Douglas,
I had the same problem as Jonathan described in his post "PET processing
seg fault with mri_glmfit --mrtm1" (
https://mail.nmr.mgh.harvard.edu/pipermail//freesurfer/2016-January/043144.html
).
In my case, I used this command:
mri_glmfit --y gtmpvc/km.hb.tac.nii.gz --mrtm1 gtmpvc/km.ref.tac.dat
time.dat --o mrtm1 --no-est-fwhm --nii.gz
And I got this message:
/Applications/freesurfer/bin/mri_glmfit: line 3: 27756 Segmentation fault:
11 mri_glmfit.bin "$@"
Following your advice, I checked if km.hb.tac.nii.gz was all 0 using
hb = fast_vol2mat( MRIread('km.hb.tac.nii.gz'));
plot(hb)
in matlab, but that is not the case
[image: Inline image 1]
I also checked the table.dat format and it was correct, and I tried using
mri_glmfit.bin command insted, but it did not work.
Could you give me some advice, so I can keep running the PET surfer
pipeline?
Thank you in advance and kind regards,
CP
