老师您好，我看了很多文献里都有做完功能连接以后提取Z值然后和量表等资料做相关，但是我不清楚这个z值是怎么提取的呢？我看的文献里都没有写这个具体过程。可以用rest 软件提取吗？
老师，
请问问为什么 resting-state fMRI 是从 0.01~0.08Hz 呢。。。？ 与呼吸和心跳等频率是否直接相关？
先谢谢！
各位老师, 有个VBM的问题,
谢谢！
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?
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!
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！
想问一下头顶那些白色得是什么引起得？数据是不是不能用了
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！
Hello,
I am using REST Functional Connectivity tool to generate the zFC maps and am having this problem:
