Discuss (controversial) issues

各位老师，大家好，我的一篇文章大修，是研究基因型与疾病关系的。

我首先用VBM，做了基因型与组间（正常/患病）的方差分析，得到有两个cluster存在交互作用，然后用这两个cluster做全脑的FC，再做FC的方差分析

审稿人除了指出样本和效应量的问题以外，还提出“Is there a bias for picking up ROI seeds correlated with GENE and then evaluating the relationship between GENE with the FC connected to these seed ROIs?'

不知道审稿人的这个问题怎么回答合适？多谢指教！

Normalization

Hi, I finished all the preprocessing step for RAT resting state without any error message. when Im checking Quality control of my data : Im overlaying functional images on their structural image after co registration and normalization....its seems perfectly overlap But when Im overlapping my functional and structural images with template that is provided in the template folder thee are not perfectly overlap. do you know what might be the error ? just to let you know that i have resize my voxel by factor of 10 at the beginning Thank you for your kind help

有关DPABI中smooth的一些问题

我想用中文提问 (I want to post in Chinese)
     大家好，
   
      第一次使用DPABI，在使用过程中有一些疑惑，烦请各位老师解惑：
    
      1.视频中讲计算degree centrality的时候，不能使用smooth后的数据，那么在计算完DC后需要平滑吗？我都试了下，发现两次的结果相差较大。（备注：我使用的是第三处的smooth，见下文）
    
     2. 我先用smooth后的数据计算了ALFF和fALFF；跑完之后，用未经过smooth的数据计算ReHo和FC，然后选择了‘smooth derivatives’。我现在的疑问是，选择这个选项后会不会把我之前算好的ALFF和fALFF重新平滑了？我发现results文件中ALFF和fALFF文件夹日期有改动。
    

任务态预处理回归无关信号

Hi，

麻烦问一下任务态的数据是否不能够使用白质、头动信号回归的？我发现回归以后无法用GLM建模，会出现no inmask voxels的报错。不只是DPABI，用CPAC等其它pipeline工具包也会出现这个问题。是否回归去除artefact的方法只适用于rest数据？非常感谢！

Warning "The detected time points is 2, it is different from the predetermined time points (260)", but it's not!

Hello,

I encountered yet another error. For some subjects DPRSFA shows me a warning message saying "The detected time points is 2, it is different from the predetermined time points (260), check your data!". The problem is that my data has 260 volumes so I don't understand the meaning of this. Does anyone have an idea?

Thank you so much!
