infinite t-stat/z-stat

[gjoue]

Hi,
Sometimes I get infinite t-stat and/or z-stat values in my pTFCE-enhanced images. I guess this is somehow related to what Mark Jenkinson and Mark Woolrich describe in their tech report? I know Stephen Fromm has turned their workaround into a Matlab function, but is there a way to work around this already in pTFCE?
Many thanks,
Gina

Thanks a lot, this is a very nice recommendation!
Put it on the roadmap.

Do you experience this behavior with the R-package or the SPM toolbox?

As the T/Z-values becoming inf with pTFCE are usually already very high (and statistically significant) anyway, it might be a good solution for these peaks to simply report the unenhanced p-value.

Hi Tamas!
I get these infiinite T/Z-vals in the SPM toolbox version.
And thank you very much for all the really useful details, suggestions, and taking the time out to carefully answer my long posts in detail -- really appreciate that!!
