resting data平滑核与p值的设定

论坛老师们：
     最近积累了几个问题，想问问大家：
     1、平滑核的选择。最近遇到文章返修，reviewer说4mm不是最合适，虽然没有继续揪这个问题，但我想看看大家的看法，因为有时候这个选择也会一定程度上影响到结果，是否随便选哪个都不算是大问题？

about ALFF calculate in REST and DPARSF

Submitted by Qing Zhao on Wed, 08/01/2012 - 01:57

I found that the Fourier translation cost most time of the ALFF and fALFF calculating.
Maybe we need not to move the power spectrum files after ALFF so if you want fALFF later, REST can run it based on these files and save lots of times, especially when there are many many subjects.

I also wonder if you pick both ALFF and fALFF, how will DPARSF do this?
