Hello,

关于Dpabi预处理Reorient和头动的问题

Submitted by ly666 on Wed, 10/03/2018 - 08:26

各位老师好，

         最近重处理了一些数据遇到了一些问题：

        1、由于重新处理数据，在reorient步骤多少有些差异，似乎这个差异会影响最后的预处理结果？如果用afni的3dwarp，可能不需要手动调节？

       2、不知道头动校正时Dpabi时使用第一个时间点图像还是平均头像做基线检测那6个头动参数的？因为同个数据删除了最后5个时间点发现最大的平动参数比没删之前要大，会是reorient不同影响么？

谢谢老师！

Explanation of Result outputs

Submitted by Vivek Trivedi on Thu, 09/27/2018 - 02:18

Dear DPABI experts:

I am a bit confused regarding the outputs of the files in the 'Results' folder. There seem to be individual subject image files, m* files and z* files. My questions are: 

1. What do these different files represent?

2. Which files should I use for standardization and statistical analysis?

3. Would it make sense to use an ANOVA test to compare the ReHo results z* files of 3 groups (Control, Early Disease, Advanced Disease)? Will this test be able to show me significant differences in Regional Homogeneity between the 3 groups?

不同机器扫描出来的MRI数据能合并分析吗吗？还有就是同一种机器不同参数扫描出来的数据可以合并分析吗

How can I get the color bar to show on the montage view ?

Submitted by lizhe8785 on Fri, 08/31/2018 - 20:26

Hi Dr Yan,

How can I get the color bar to show on the montage view ? I saw there was a guiding said "you add "+" or "-" flag at the end in "Add Overlay's Colorbar" entry, DPABI_VIEW will use full colormap to display the overlay". But I can't find where the "Add Overlay's Colorbar"  is. Can you show me? Thank you!
