Dear Jesper, Eric & Mike,
> Could you give a more detailed description of how you enter the model,
and the full error message.
This is the design I entered:
PET/SPECT Models
Single-Subject: covariates only
I select 16 scans
# Covariates: 1
[16] covariate: [ 38 32 38 29 31 26 32 34 32 46 28 35 35 34 34 40]
covariate: centre? *around overall mean
nuisance variables: 0
Global Normalisation: Proportional Scaling
PropSca global mean to 50
Threshold masking: proportional
Analysis threshold (proportional of global) : 0.8
Global calculation: *mean voxel value (within per image fullmean/8
mask)
The “segmentation fault” happens when I try to visualize thre process
results:
Results
Mask with other contrast(s): no
Title for comparison:
Corrected height threshold: no
Threshold {T or p value} 0.001
& extent threshold {voxels} 20
At this point SPM halts and this is the prompt message:

Segmentation Fault (core dumped)
I also tried with a bigger group size (30) and had the “segmentation
fault” message too.
I have no problems with “Multisubject: covariates only” in SPM96
(Proportional Scaling/ No Grand Mean Scaling/ Gray Matter threshold:
0.8)
Many thanks. Griselda
