请教关于mixed effect analysis问题

严老师:

    您好!我想看实验组和对照组治疗前后ALFF差异,是不是应该用mixed effect analysis?我用DPABI做mixed effect analysis后,得出的Interaction_F.nii在Viewer里显示的图像同ANOVA图像,只能看出哪些区域有差异,但是不能看出具体哪些是升高的,哪些是降低的。假设实验组治疗后壳核ALFF升高,而对照组治疗后壳核ALFF不变或降低,请问如果我想看两个组在壳核ALFF的变化不同,我该用什么方法呢?

    希望您能在百忙中帮忙解答,谢谢您!

Possible to create interface pictures and montages by script using function of DPABI viewer?

Hi,

I'm trying to generate the interface and montage pictures automatically via a script. That is, I want to 

1. Load a nifti file (blobs) onto a T1 anatomical image (like in the viewer)

2. Load a colormap for the blobs

3. Specify an x/y/z coordinate

4. Specify an overlay transparency value (i.e. want to set it to 0 )

5. Create the interface pictures automatically (and save to a folder) at the specified coordinates (just like it can be done with the "save interface as Picture" button only via a function/script)

Time series analysis and ROI signal folder

Hi all, 

So after processing and extracting roi signals, the next step is for me to analyze the roi signals of my subjects using SPSS. Does anyone know what type of analyisis I should carry out on SPSS as I have two groups, one healthy and the other  have Alzheimers.
Whic do I use rregression or corellation.

Also what does the different type of file mean in the results folder for roi extraction. does  Z mean zett?

 

much appreciation, really  benefiting from this program!!

Normalize时报错No T1 image has been found

严老师:

          你好。我在使用DPARSF做Normalize时,采用的是EPI模板。但仍然报错“No T1 image has been found.”但之前的所有步骤均未选择读取T1像。

          如果我用DPARSFA做,则报错

unable launch the DPABI under Linux

hi,

    when I use the matlab under Linux system, once I tyoe "dpabi", the matlab will be jamed and the other previously launched procedure, such as REST, also could not   continue to use.  The matlab was like dead and I can do nothing. When 25 mins later, the dpabi gui was shown up. However, when I further clicked the "viewer" or other button, there was an error appearing:"undefined function or variable ‘DPABI_VIEW'".
