Positive not negative correlation maps in REST

Submitted by merrf on Mon, 07/26/2010 - 13:05

Dear REST developers and experts
 
To the first, I really appreciate for providing a wonderful free software.
I've also attached the following query to the SPM mailing list.
 
I'm analysing seed-based (hippocampus) resting-state functional connectivity between patient and control groups by using spm8 and especially REST program.
The resulting zFC maps of include both positive and negative correlations.

dparsf做功能连接，生成的结果中ROI没用用实名标识，而是用ROI1，ROI2，ROI3，.......，怎么辨认该ROI是什么？

Submitted by xuercan on Mon, 08/02/2010 - 13:04

在dparsf中假如用4个ROI做功能连接，如A,B,C,D，生成的结果为ROI1，ROI2，ROI3，ROI4，请问，这里ROI1-4与A-D的对应原则是什么？是仅仅按加入时的顺序还是按ASCII的大小排序，请明示？

About Masks in REST have different origin coordinate with SPM images

Submitted by mwst on Wed, 08/04/2010 - 11:43

老师：
     你好，我使用rest提供的mask来提取全脑、CSF、白质的信号，但是我发现这些mask的中心点坐标即origin coordinate是0，而SPM里面的图像则不是。所以无论使用MRIcro的overlay还是SPM的checkreg功能，rest提供的mask与SPM里面的图像都不配，这样的话是否提取mask内的信号是可靠有效的呢？因为我不知道其计算的原理，所以在此发问，我的图像都已经是重采样后与mask相同的体素大小和坐标框。
   请老师解释一下。

请教一下单样本T检验的问题

Submitted by demonpupil on Mon, 08/09/2010 - 09:44


老师，您好：
  
  请教一个问题，我有病人组16个被试，利用DPARSF计算其ALFF值，然后利用单样本T检验得到病人组内ALFF显著高于全脑均值的区域A,B,C
  
  问题：如果我想单独得到被试甲的ALFF显著高于全脑均值的区域在哪里，我需要用什么方法，什么检验？刚才我单独利用被试甲或被试乙的mALFF分别做了一个单样本T检验，之后用REST slice viewer发现什么结果都没有。是否是单样本T检验要求纳入被试人数需要大于3个的原因？

盼回答，谢谢！！
