citations or references about VMHC, GCA and degree centrality of REST toolbox

Submitted by chlai on Sun, 06/09/2013 - 21:50

Dear REST experts:

I noticed that there are several new functions of REST v1.8 when compared to previous version, such as VMHC, degree centrality and GCA.

Can anybody tell me the citations or references for these new functions?

Thank you.

求大鼠脑功能模板和全脑MASK

Submitted by chenyuchen1989 on Tue, 06/11/2013 - 23:02

老师您好：
       初次做动物的脑功能分析。不知道您是否有大鼠的标准化模板？或者哪位大侠有模板的？应该就是中科院高能物理研究所那种。能否提供给学生使用一下？谢谢！
还有，做rest分析时的mask应该用哪一种？这个我也没有。特向老师求教。谢谢！

functional connectivity maps

Submitted by Helen Sawaya on Thu, 06/13/2013 - 15:45

 Dear all,

I am new to DPARSF and I have a question concerning the z transformed functional connectivity maps. I am a bit surprised at the results because the z values of my maps are pretty low (most are between -0.6 and 1). I did not globally regress my images and I expect at least a few voxels to have values of 3 or 4. Anyone has any ideas as to why that is happening?

modulation in VBM (in DPARSFA)

Submitted by Chen0075 on Fri, 06/14/2013 - 02:52

 各位老师, 有个VBM的问题, 

在做VBM的modulation时候我们经常这样选择：
单击Modulated normalized选择“affine+non-linear only”。这里的affine+non-linear only是什么意义，是说T1像经过affine和non-linear两次normalization，然后得到一幅MNI的图像？
在DPARSFA的VBM里面是如何选择normalization和modulation过程的。

谢谢！
