Dear SPMers,
We would like to disable the analysis threshold to conduct stats in
regions affected by susceptibility artifact. We have followed John's Gems
to set sPM.xM.TH to -Inf and set an explicit mask by modifying SPM.xM.VM.
We created the explicit mask by 1) adding the gray and white matter
2)smoothing the image (8mm) 3)masking all points. We selected double as
our output type but otherwise kept the defaults. The explicit image is
written out in NII format.
When generating the stats table. The following errors are generated:
Warning: Returning NaN for out of range arguments
> In spm_Pcdf at 88
In spm_P_RF at 106
In spm_P at 48
In spm_list at 489
In addition, the cluster statistics are all reported with NaN.
I am working in SPM5, but believe this problem would apply to any version.
Any suggestions.
Thanks,
Jennifer
