modulation in VBM (in DPARSFA)

 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!

functional connectivity maps

 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?

Why linear trend should be removed before filtering?

Dear all,

Here is a conversation long time ago on the necessity of removing linear trend before filtering, if we think linear trend is a kind of noise. Hope this information is helpful for some of us!

scanner drift and temporal filtering

老师,请问下:低频的 scanner drift 可以在滤波的时候被抑制,为什么之前还需要对它进行 nuisance covariate regression 呢? 是否回归这一步是为了减弱它对其它频率的影响。。。?

谢谢!

求大鼠脑功能模板和全脑MASK

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!

error using horzcat while trying to analyze FC with REST

 Hello, 

I am using REST Functional Connectivity tool to generate the zFC maps and am having this problem:

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

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.
