报结果

Submitted by yangshuo on Wed, 06/13/2012 - 09:16

 老师你好，请问我用rest sliceviewer 的CLreporter报结果，用的Alphasim 校正，6平滑，p<0.01，应该是cluster size 40，rmm 5吧？那我的结果里面凡是小于40个cluster size 的脑区都不能报了吧？
  这里附上一个clusters

Number of voxels: 271
Peak MNI coordinate: -3 -90  30
Peak MNI coordinate region:  // Left Cerebrum // Occipital Lobe // Cuneus // Gray Matter // brodmann area 19 // Cuneus_L (aal)

Indipendent Component Analysis and non stationarity

Submitted by Giuseppe on Mon, 06/11/2012 - 10:56

Hi all, I'm just registered at this forum.
I'm studying Indipendent Component Analysis. I noted that it works only with time stationary processes, and fail in presence of non time stationary ones (exponential ramp, linear ramp, etc.). Are there other non-parametric techniques of blind source separation that work in in these cases? I found only parametric methods until now.
