REST AlphaSim for VBM

Submitted by dm7941a on Thu, 09/11/2014 - 01:49

 Hi!

I'm trying to use REST Alpha Sim to do a Montecarlo simulation for VBM. I am using FWHM of 8, but cannot figure out what to do for rmm. I read that the default edge connected is 18, but I have seen a range of rmm. How do you decide what to use? Also, what should I use for the Mask? The Spm T file?

Any help would be appreciated.

There are three kind of rmm numbers (4, 5, and 6) in REST, representing different connection criterior (node, edge, and surface). I think anyone is acceptable.

The "Mask" is the mask image when your did statistic analysis.
